Why Its Important to See a Doctor Premature ventricular contractions PVCs are a form of irregular heartbeat These extra beats are usually not harmful and will disappear on their own Doctors will monitor your heartbeat and look for other vital signs They might order a Holter monitor a device that tracks your hearts electrical impulses over a period of 24 to 48 hours They can also request blood tests for checking your electrolyte levels and thyroid hormones Diagnosis PVCs are caused by electrical impulses that misfire through the SA node a structure located in the lower chambers of the heart This delay the next heartbeat causing the feeling of fluttering or skipped beats in the chest PVCs may occur alone or in repeated patterns Doublets are two consecutive PVCs Ventricular tachycardia refers to three or more consecutive ones While some people dont have any symptoms at all Others experience heart palpitations that can be felt as the heart beating faster or slower Other signs are dizziness fatigue or feeling unwell Many people who experience occasional PVCs dont require any treatment If a person has frequent episodes doctors may recommend a change in diet or lifestyle including a reduction in caffeine alcohol and stress They can prescribe medication such as betablockers and calcium channel blockers to lower blood pressure and slow the heart rate Doctors will ask the patient about their medical history and then perform an examination of the body to assess their general health They may also employ an electrocardiogram ECG to take a snapshot of the hearts electrical activity or a Holter monitor which is worn for longer periods and captures the hearts rhythms over time In certain cases doctors may require blood tests to determine if there is an electrolyte imbalance or toxic effects from drugs A pvc physician may refer a patient to an electrophysiologist or specialist in heart rhythm disorders for further evaluation The doctor can confirm the diagnosis of PVCs and determine whether they are benign or malignant PVCs are fairly common and rarely cause any problems unless they occur frequently over a long time This can cause a weakening in the heart muscle or a condition known as pvcinduced cardiac myopathy window doctor is more common in older people or those who have some type of heart disease It can also happen in healthy people with a normal heart although this is more likely in those who exercise regularly It is not a major problem but it is important to consult your physician if you notice symptoms such as fatigue or fainting occur Treatment PVCs are not harmful and do not cause symptoms in a lot of people They dont require treatment If you feel like your heart is racing or not making a beat its best to seek out a physician immediately A cardiologist will interview you and then perform an examination of your body listening to your heart with the stethoscope in order to detect any irregular beats Youll also undergo an electrocardiogram which records the electrical signals of your heart allowing you to identify any arrhythmias If an arrhythmia is detected then an allday Holter monitor or a portable ECG is required to capture the irregular rhythm for longer durations of time These devices can help doctors determine whether you have PVCs and their cause which could be due to an imbalance in electrolytes toxic drugs or other causes You might be required to undergo an echocardiogram an ultrasound of your heart to determine the health of your heart is in good order and to look for structural issues that could lead to PVCs You could also have a stress test to see how your heart responds to physical activity can increase the frequency of your pvcs You may also undergo blood tests to assess your thyroid magnesium and potassium hormone levels to determine whether they are low which could contribute to the formation of PVCs Once your doctor has confirmed that you have PVCs and has ruled out any serious illnesses the decision on whether to treat them will be based on the extent to which they impact your life and how frequently they occur If they happen only on occasion and dont trigger any symptoms its unlikely that your doctor will recommend any medication to lessen their frequency or severity If you experience frequent PVCs that cause the sensation of palpitations or other symptoms such as feeling lightheaded or like youre about to faint your doctor might recommend medications like beta blockers or calcium channel blockers Changes in lifestyle such as abstaining from smoking caffeine and excessive stress can also reduce the frequency of these abnormal pulses Prevention PVCs can cause no symptoms or heart palpitations which can feel like skipped beats or flutterings in the chest Sometimes these episodes can cause an increase in pressure or fullness in the chest and other times they can make a person feel faint These episodes are caused by the heart not pumping as efficiently as it should PVCs are associated with an increased risk of dilated cardiomyopathy This is a condition where the heart expands and becomes in a position to not pump blood PVCs are usually caused by changes in the bodys chemistry This includes the release of thyroid hormones and adrenaline and alcohol consumption or caffeine Lack of exercise can trigger these episodes like stress or excess weight Certain people find that a change in diet helps reduce their PVCs For instance they could avoid foods that contain preservatives that can cause a disturbance in the heart rhythm such as disodium guanylate E621 disodium inosinate E627 diazole sodium E282283 Consume more fruits and vegetables to ensure that you get sufficient magnesium Regular health checks are important and include annual physicals These can help diagnose any heart issues that could be causing your PVCs Also you should adhere to a healthy eating plan and refrain from smoking which can increase the frequency of your episodes A survey of 14 regular hospital wards revealed that healthcare staff were generally aware of preventive measures to avoid the infection caused by vascular catheters but their selfassessment of conformity to these practices was low After a feedback program that improved compliance on certain areas but was still very low This suggests that education is required to implement preventive measures and those wards that are less than compliant should be targeted for monitoring of infection This information could be used to guide the implementation of further quality improvement initiatives on these wards This will likely require more education and training for personnel It will also require making sure that the appropriate materials are in place for the implementing of the preventive measures Symptoms Premature ventricular contractions can cause your heart to skip beats or to flutter These arrhythmias may be harmless or they may be a sign of serious heart problems In healthy individuals occasional PVCs arent a problem and they usually disappear by themselves If youve got many of them it can cause dizziness or weakness If youre worried you might be experiencing dizziness or weakness talk to your doctor about them They may have to identify the problem by taking an medical history and conducting a physical exam Theyll likely also need to do an electrocardiogram ECG or EKG or other tests A short ECG test allows your doctor to see the pulse of your heart moving through your body over the course of a brief period The test will determine if you have PVCs Your doctor might also want to do an overnight or 24hour Holter monitor which monitors your heartbeat for longer durations of time This can help distinguish PVCs from other arrhythmias which cause heart palpitations You can wear an event monitor a portable device that tracks your hearts rhythm over 30 days Other tests for the heart may be needed depending on the reason for your PVCs For instance an cardiologist may test your blood pressure and perform an ultrasound of the heart echocardiogram These tests will determine whether you are suffering from a condition such as heart failure mitral valve prolapse or cardiomyopathy Your doctor may also have to conduct an examination of your blood to determine what the problem is in your electrolytes like low potassium or high levels of calcium This could indicate that you have PVCs or a different health issue such as anemia or anxiety disorders You could be referred to an electrophysiologist a specialist who specializes in treating irregular heart rhythms If you suffer from structural heart disease the doctor may need to perform additional tests such as an MRI or CT scan of your chest These tests will determine whether your heart is damaged and how severe the damage is In some instances doctors may suggest a pacemaker to treat the issue that causes the PVCs
