Pvc Doctor Tips From The Best In The Industry
How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) typically regulates your heart's rhythm. Electrical signals are transmitted to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that normally starts your heartbeat in a part known as the sinus node (also called the sinoatrial node or SA node) isn't. The impulse actually begins in the ventricles and causes an untimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or is like it's fluttering. They can occur infrequently and cause no symptoms, or they may occur frequently enough to affect your daily life. Your doctor may prescribe medication if they are frequent or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is especially the case if they are caused by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

PVCs can cause symptoms, such as a sensation of your heart skipping one beat, or even the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more apparent when you exercise or consume certain foods or drinks. People who suffer from chronic anxiety or stress can have more PVCs and certain medications such as amiodarone, digoxin and cocaine can increase the likelihood of developing them.

If you are experiencing occasional PVCs, your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks, like caffeine and alcohol. You can also lower your stress by getting enough sleep and exercising.

If you have a lot of PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation, which destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is typically successful in treating PVCs which reduce symptoms, but it does not stop them from recurring in the future. In some cases it may increase your risk of atrial fibrillation (AFib), which can lead to a stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, may make your heart appear to skip or flutter a beat. These heartbeats that are not normal can be harmless, but you might be advised to consult your physician when they occur frequently or if you experience symptoms such as dizziness or fatigue.

The electrical signals typically begin at the sinoatrial junction, which is in the top right-hand side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles contract to propel blood into your lungs and then return to your heart and start the next cycle of pumping. A PVC starts at a different spot, the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs occur, the heart may appear to be skipping a beat or pounding. If window doctor experience only just a few episodes and there are no other symptoms the cardiologist will likely not prescribe treatment. But if you have a number of PVCs the doctor may suggest an electrocardiogram, or ECG to determine your heart rate over 24 hours. The doctor may also suggest wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

Anyone who has suffered an earlier heart attack or cardiomyopathy, a condition which affects the heart's blood flow - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. This includes avoiding alcohol, caffeine and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you have frequent PVCs, even if you don't have any other signs, you should see a cardiologist. These irregular heartbeats could signal a problem with the structure of your heart or lungs and if they occur frequently enough, can weaken the heart muscle. However, most people with PVCs don't have any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, especially if they are frequent and intense. People who experience them regularly might feel faint. Exercise can cause PVCs, but a lot of athletes who experience these symptoms do not have heart or health problems. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist might also use an echocardiogram that uses ultrasound to look at the heart and determine how it's working.

Often, a doctor will be able to determine if a person has PVCs from a history and physical exam. Sometimes, they may not be aware of them until they examine the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They can be used to detect heart disease in the event of any reason to be concerned.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. If your symptoms are causing you discomfort or make you be anxious, avoiding alcohol, caffeine and over-the counter decongestants, and decreasing stress can aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also decrease the likelihood of PVCs. If your symptoms persist or severe, talk to your doctor about medication that could be able to control them.

Treatment


If PVCs are rare or do not cause symptoms, they rarely need treatment. If you have them often or frequently, your doctor may wish to look for other heart conditions and recommend lifestyle changes or medicine. You might also get an operation to rid yourself of them (called radiofrequency catheter ablation).

When you have PVCs The electrical signal that triggers your heartbeat is generated from a place outside of the sinoatrial node (SA node) located in the upper right part of your heart. It can feel like your heart skips a beat or has extra beats. It's not clear what causes these symptoms, but they're frequent in those with other heart issues. PVCs may increase in frequency with age and might happen more often during exercises.

A doctor should perform an ECG and an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be performed to find other causes of the increased beats.

Most people with PVCs do not experience any problems and can enjoy an ordinary life. They can increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, that means the heart muscle gets weaker and is having difficulty pumping blood through your body.

Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid window doctor that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. Sleep and stress are equally crucial. Certain medications can increase your risk of getting PVCs. If you are taking any of these medicines it is crucial to follow the advice of your doctor regarding eating a healthy diet exercising, as well as taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. Certain people may require an organ transplant.
