Why Pvc Doctor Is Harder Than You Imagine
How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.

The heart's rhythm is controlled by a group of fibers located in the upper right-hand part of your heart. This is called the sinoatrial node or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.

Causes

PVCs are caused when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. Instead, this link starts in a different area of your heart, the ventricles, and causes an untimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart beats faster or feels fluttering. They can happen infrequently and not cause any symptoms, or they can happen often enough to interfere with your quality of life. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor might treat them with medication.

PVCs are generally harmless and do not increase your risk of developing heart disease. Regular PVCs however, may weaken the heart muscle over time. This is especially true if they are caused by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.

PVCs can trigger symptoms such as a feeling of your heart beating a beat, or fluttering. You may also feel breathless. The fluttering may be more apparent when you exercise, or eat or drink certain drinks or foods. People who experience chronic anxiety or stress can have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the likelihood of developing them.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medication. If they're a frequent occurrence, you may have to avoid certain drinks and foods, such as alcohol and caffeine. You can also reduce your stress levels by taking enough rest and exercising.

If you have many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. This destroys cells that cause PVCs. Electrophysiologists are the ones who execute this procedure. It is usually effective in treating PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In certain cases it can increase your risk of atrial fibrillation (AFib) which could cause stroke. This isn't common, but it can be life-threatening.

Symptoms

Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or flutter. These extra heartbeats can be harmless, but you might be advised to consult your physician if they are frequent or if you are experiencing symptoms such as dizziness or fatigue.

The normal electrical signals start in the sinoatrial area, which is located in the upper right corner of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles contract to propel blood into the lungs, and return to the heart to begin the next pumping cycle. A PVC begins in a different place in the Purkinje fibers are located in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel like it is beating faster or slower. If you have just a few episodes but no other symptoms, the doctor will probably not treat you. However, if you have large number of PVCs the doctor may recommend an electrocardiogram, or ECG, to measure your heartbeat over a 24-hour period. He or she may also recommend wearing a Holter monitor, which will record the heart's rhythm over time to see how many PVCs you have.

If you've had a previous heart attack or cardiomyopathy - a condition which affects the heart's blood flow - must take their PVCs seriously and consult a cardiologist regarding lifestyle modifications. Those include the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough sleep. A cardiologist may also prescribe medication to slow the heartbeat like beta blockers.

If you are experiencing frequent PVCs even if do not have any other symptoms you should see a cardiologist. These extra heartbeats may signal a problem with the structure of your heart or lungs, and if they occur frequently enough, can weaken your heart muscle. The majority of people with PVCs do not experience any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, particularly when they're frequent or intense. People who experience them often may feel weak. Exercise can cause them, but many athletes who suffer from them have no heart or health issues. PVCs may show up in tests like an electrocardiogram or a Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

A doctor is often able to tell if a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes it is possible that they only be able to detect PVCs when they examine patients for a different reason, such as after an accident or surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and could be utilized in the event of any suspicion of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are causing you discomfort or cause you to be anxious, avoiding alcohol, caffeine, and over the prescription decongestants, as well as decreasing stress can aid. Regular exercise, being at a healthy weight, and drinking enough water can also help reduce the frequency of PVCs. If your symptoms persist or are extreme, talk with your physician about possible medication options to treat these symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they don't usually require treatment. If you are frequently affected, your doctor may want to look for other heart issues and suggest lifestyle changes or medication. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

When you have PVCs the electrical signal that causes your heartbeat begins somewhere outside of the sinoatrial node (SA node) located in the upper right side of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. They're more common among people suffering from heart disease however it's unclear what causes them. PVCs can increase in frequency as you age, and may occur more frequently during exercising.

A doctor should perform an ECG along with an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. The doctor will also perform an exercise stress test to determine if the extra heartbeats are related to physical exercise. To determine whether there are other reasons for the extra beats an invasive heart catheterization or an MRI is possible.


Most people with PVCs do not have any issues and live an ordinary life. They could increase your risk for heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some cases, this means that the heart muscle becomes weaker and is unable to pump blood throughout the body.

A healthy, regular diet and plenty of exercise can help reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat and restrict your intake of tobacco and caffeine. Sleep and stress are equally crucial. Certain medications can increase your risk of PVCs. So if you take one of these medicines it is important to follow your doctor's instructions about eating well, exercising and taking your medication.

In studies of patients with PVC burdens that are high (more than 20% of total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Some people may need a heart transplant.
