How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. If they happen frequently, PVCs may weaken your heart and increase your chance of suffering from heart failure.

A bundle of fibers in the upper right part of your heart (the sinoatrial or SA node) usually controls your heart rhythm. Electrical signals travel to the ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that usually starts your heartbeat in a region known as the sinus node (also called the sinoatrial or SA Node) doesn't. The impulse actually starts in the ventricles and causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. It could feel as if the heart beats faster or feels like it is fluttering. They may occur infrequently and not cause any symptoms, but they could be frequent enough to affect your standard of life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.

For most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.

PVCs can trigger symptoms like a feeling of your heart racing one beat, or even the feeling of your heart fluttering. You may also feel exhausted. The fluttering may be more apparent when you exercise or have certain foods or drinks. PVCs are more common for those who suffer from chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, can increase the risk.

If you experience occasional PVCs Your doctor might suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks such as alcohol and caffeine. You can also take steps to reduce your stress, and make sure you get enough sleep and exercise.

If you've got a lot of PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. Electrophysiologists are the ones who carry out this procedure. It is typically effective in treating PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases, it can increase your risk of having atrial fibrillation (AFib), which can cause stroke. It is not common but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs may cause your heart to skip or be fluttering. These extra heartbeats can be harmless, but you might want to consult your doctor when they occur frequently or if you notice symptoms like dizziness or fatigue.

The normal electrical signals start in the sinoatrial region, which is in the upper right part of the heart. They then travel to the lower chambers, or ventricles, which pump blood. The ventricles contract to force blood into the lungs. They return to the heart's center to begin the next cycle of pumping. However, a Pvc doctor starts at a different spot and is located in the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur, they can make the heart pound or feel as if it skipped one beat. If you experience just a few episodes but no other symptoms, the doctor probably won't be able to treat you. If you've got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. They may also suggest wearing a Holter monitor that will track the heart's rhythm over time to determine the number of PVCs you have.

Anyone who has suffered a previous heart attack or cardiomyopathy, an illness that affects the heart's blood flow - should take their PVCs very seriously and speak to an expert in cardiology about lifestyle modifications. This includes cutting down on caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist can also prescribe medication to slow the heartbeat for example, a beta blocker.

If you have frequent PVCs even if you do not have any other symptoms, you should consult an expert in cardiology. These irregular heartbeats could point to an issue with the structure of your heart or other health conditions and, over time, when they are frequent enough, they could weaken the heart muscle. Most people who suffer from PVCs don't experience any issues. They simply want to be aware that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, especially if they're frequent or intense. People who experience them frequently might feel faint. They can also happen with exercising, but most athletes who get them don't have any problems with their health or heart. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors that record electrical signals from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.

A doctor is often able to tell whether a patient has PVCs by looking at them and taking a medical history. Sometimes, they may only notice them while examining the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They can be used to detect cardiac disease if there is any reason to be concerned.

If your cardiologist determines that your heart's structure is normal, reassurance will be the only treatment required. If your symptoms are troubling or cause you to feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are severe, speak to your doctor about possible medications that can control the symptoms.

Treatment

If PVCs do not cause any symptoms or occur rarely they aren't usually in need of treatment. If they are frequent, your doctor might need to examine for heart issues or suggest lifestyle changes. You could also have a procedure (called radiofrequency cathode ablation) to get rid them.

If you have PVCs The electrical signal that causes your heartbeat starts somewhere other than the sinoatrial node (SA node) located in the upper right part of your heart. This can make it feel like your heart skips a beat or has extra beats. It's not known what causes them, but they're more frequent in those with other heart conditions. PVCs may increase in frequency as you age, and they could be more frequent during exercises.

A doctor should perform an ECG as well as an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. The glazing doctor may also conduct an exercise stress test to determine if the additional heartbeats are caused by physical activity. To find out whether there are other reasons for the extra beatings, a heart catheterization or cardiac MRI is possible.

Most people with PVCs do not suffer from any issues and can live an ordinary life. They may increase the risk of developing dangerous heart rhythm disorders, especially if they occur in certain patterns. In some cases, this means that the heart muscle gets weaker and it is more difficult to pump blood throughout your body.

Regular exercise and a healthy diet can lower your chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of caffeine and tobacco. Sleep and stress are equally crucial. Some medicines may also increase your risk of getting PVCs. If you are taking any of these medications, it is important to follow your doctor's advice regarding healthy eating exercising, as well as taking your medication.

Studies of patients suffering from a high amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require an organ transplant.
