How a VC Can Affect Your Heart
PVCs are common and can be experienced by a wide range of people without causing any issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The heart's rhythm is usually controlled by a bundle of nerve fibers situated in the upper right corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel to lower heart chambers or ventricles.
Causes
PVCs occur by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually begins in the ventricles and causes a mistimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can occur rarely, causing no symptoms, but they can occur frequently enough to affect your standard of living. If they occur frequently or cause weakness,

PVCs are generally harmless and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart disease such as 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 beating one beat, or even the feeling of your heart fluttering. It is also possible to feel breathless. The fluttering may be more evident if you exercise, or consume certain drinks or foods. PVCs are more prevalent in those suffering from chronic stress or anxiety. Some medications, like digoxin, amiodarone or cocaine, may increase the risk of developing PVCs.
If you have occasional PVCs Your doctor might suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor may recommend avoiding certain foods and drinks such as alcohol and caffeine. You can also reduce your stress levels, and take advantage of plenty of rest and exercise.
If you have many PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. It is generally successful in treating the PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib),

Symptoms
Premature ventricular contractions, also known as PVCs, can cause your heart seem to skip or flutter a beat. These extra heartbeats are usually harmless, but you should talk to your doctor if you have frequent episodes or signs like dizziness or weakness.
The normal electrical signals start in the sinoatrial area, which is located in the upper right-hand part of the heart. They then travel to the lower chambers, also known as ventricles, that pump blood. Then, the ventricles expand to push blood into your lungs, and then return to your heart to start the next cycle of pumping. A PVC begins at a different spot, the Purkinje fibres bundle in the bottom left of the heart.
When PVCs happen, the heart may appear to be skipping a beat or pounding. If you have a few episodes and no other symptoms, your doctor probably won't be able to treat you. If you've got a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, also known as an ECG to gauge the heart's rate over a 24-hour period. The doctor may also suggest wearing a Holter monitor, which will record your heart rhythm over time to see how many PVCs you have.
People who have suffered an earlier heart attack or cardiomyopathy, an illness that affects the heart's blood flow - must take their PVCs seriously and speak to a cardiologist about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can prescribe medications to slow heartbeat, for example, beta blockers.
Even if you don't have any other indications it is still recommended to have PVCs examined by an cardiologist if they occur often. These irregular heartbeats could be a sign of an issue with the structure of your heart or other health conditions and, over time if they occur often enough, they could weaken the heart muscle. However, most people suffering from PVCs don't have any issues. They simply want to be aware that the fluttering or skipping heartbeats aren't normal.
Diagnosis
PVCs can feel like heartbeats that are fluttering, especially if they are frequent and intense. People who get lots of them may feel they're going to faint. Exercise can trigger PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors on them to record electrical signals from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.
A doctor is often able to tell the presence of PVCs by looking at them and taking a medical history. Sometimes, they may only be able to detect them when they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and could be utilized when there is a concern of heart disease.
If your cardiologist determines that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are bothersome, or cause you to feel anxious, avoiding alcohol, caffeine and over-the drug decongestants and decreasing stress can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms continue or are severe, talk with your physician about possible medication options to treat the symptoms.
Treatment
If PVCs aren't causing symptoms or happen rarely, they usually don't need treatment. If they occur frequently, your doctor might be able to look for heart problems or suggest lifestyle modifications. You could also have an operation to rid yourself of them (called radiofrequency catheter ablation).
When you have PVCs, the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) located in the upper right side of your heart. This could cause your heart to feel as if it skips beats or has extra beats. It's not clear what causes these symptoms, but they're common in people who have other heart issues. PVCs are more frequent with age and might happen more often during exercises.
A doctor should perform an ECG along with an echocardiogram for a patient who has frequent and egress

The doctor may also perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise. To determine if there are other causes for the extra beats the heart catheterization or a cardiac MRI can be performed.
The majority of people who suffer from PVCs don't experience any problems and can enjoy a normal lifestyle. They can increase your risk for heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some cases, that means that your heart muscle gets weaker and has trouble pumping blood throughout your body.
Regular exercise and a healthy diet can lower your chances of developing PVCs.
