Learn The Pvc Doctor Tricks The Celebs Are Using
How window doctor 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 your risk for heart failure.

A bundle of fibers in the upper right-hand corner 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 happen when the electrical impulse that normally begins your heartbeat at a point known as the sinus node (also known as the sinoatrial node or SA node) isn't. The impulse actually starts in the ventricles and causes a mistimed heartbeat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart skipped a beating or feels fluttering. They can happen infrequently and not cause any symptoms, but they can occur frequently enough to affect your standard of living. Your doctor may prescribe medicine when they occur frequently or cause dizziness, weakness or fatigue.

PVCs are generally safe and do not increase your risk of developing heart disease. Regular PVCs however, may weaken your heart muscle over time. This is especially true if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

The signs of PVCs include a feeling that your heart skips a beat or flutters, and you may feel exhausted. The fluttering may be more noticeable when you exercise or consume certain drinks or food items. PVCs are more prevalent in those suffering from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone or cocaine, may increase their risk.

If you have occasional PVCs, your doctor may suggest lifestyle changes and medication. If they are a regular occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise.

If you're experiencing a lot of PVCs the doctor might suggest a medical treatment called radiofrequency catheter ablation. This destroys cells that cause PVCs. Electrophysiologists are the ones who execute this procedure. The treatment is typically effective in treating PVCs which reduce symptoms, but it does not stop them from recurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib) which can lead to a stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or be fluttering. These heartbeats that are not normal can be harmless, however you might want to consult your doctor when they occur frequently or if you notice symptoms such as dizziness or fatigue.

Normaly, electrical signals begin in the sinoatrial, located in the upper right part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. Then, the ventricles contract to propel the blood into your lungs, and then return to the heart and start the next pumping cycle. However, a PVC starts in a different place, from the bundle of fibers, known as the Purkinje fibers, located in the lower left part of the heart.

When PVCs occur, they can make the heart beat or feel like it skipped a beat. If you experience only a few episodes, and no other symptoms are present the cardiologist will likely not treat you. But if you have a lot of PVCs, the doctor may recommend an electrocardiogram, or ECG, to measure the heart's rate over a 24-hour period. He or she might also recommend wearing a Holter Monitor which tracks the heart's rhythm and count the number of PVCs.

Anyone who has suffered previously from a 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. These include avoiding caffeine, alcohol and smoking, reducing 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 do not have other symptoms, you should consult a cardiologist. These irregular heartbeats could be a sign of a problem with the structure of your heart or lungs, and if they occur often enough, they can weaken the heart muscle. Most people with PVCs do not experience any problems. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

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

Most of the time, a doctor will be able to tell whether a person has PVCs from a history and physical examination. But sometimes they might only notice them while examining the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and they might be used if there's any concern of heart disease.

If your cardiologist concludes that your heart's structure is normal, reassurance is the only treatment required. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine and other over the drug decongestants and the reduction of stress could aid. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can reduce your episodes of PVCs. If your symptoms continue or are extreme, talk to your doctor about possible medication options to treat them.


Treatment

If PVCs are rare or don't cause symptoms, they rarely require treatment. If they happen frequently your doctor may be able to look for heart conditions or recommend lifestyle adjustments. You could also have an operation (called radiofrequency cathode ablation) to get rid of them.

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. They're more common among people suffering from heart disease however it's unclear the reason behind them. PVCs are more frequent with age and might happen more often during exercising.

If a patient has frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. They may also perform an exercise stress test to determine if the extra beats are due to physical activity. To find out whether there are other reasons for the extra beats, a heart catheterization or a cardiac MRI could be conducted.

Most people who suffer from PVCs do not have any issues and can lead a normal life. However, they may increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. 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. You should avoid foods that are high in fat and sodium, and you should also restrict your intake of tobacco and caffeine. It is also important to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you are taking one of these medicines it is important to follow your doctor's instructions about a healthy diet, exercise and 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 incidence of arrhythmia-induced cardiomyopathy. This could lead to a need for a heart transplant in certain people.
