How a VC Can Affect Your Heart

Many people experience occasional PVCs with no problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

The heart's rhythm is usually controlled by a group of nerve fibers situated in the upper right corner of your heart. This is called the sinoatrial node, or pvc Doctor SA. Electrical signals travel to the ventricles, or lower chambers of the heart.

Causes

PVCs happen 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, the impulse begins in another area of your heart--the ventricles--and causes an untimed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beat or feels like it is fluttering. They can occur infrequently and have no symptoms or they may occur frequently enough to interfere with your daily life. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor could treat them with medicine.

In most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. A lot of PVCs, however, can weaken your heart muscle over time. This is especially true if they are caused by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

The signs of PVCs include a feeling that your heart beats faster or is fluttering, and you feel breathless. The fluttering can be more apparent when you exercise or eat or drink certain foods or beverages. People who suffer from chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the risk of developing them.

If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medications. If they are a regular occurrence, you may have to avoid certain foods and beverages, such as alcohol and caffeine. You can also reduce your stress door and window doctor make sure you get enough sleep and exercise.

If you're experiencing a lot of PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation. It eliminates the cells that cause PVCs. This procedure is performed by a specialist, known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms however, it doesn't prevent them from recurring in the future. In some instances it may increase your risk of atrial fibrillation (AFib) which could lead to stroke. It is not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to flutter or skip the beat. These extra heartbeats can be harmless, but you may want to consult your doctor when they occur frequently or if you are experiencing symptoms like dizziness or fatigue.

The normal electrical signals start in the sinoatrial area, which is located in the upper right part of the heart. They then travel to the lower chambers, also known as ventricles, which pump blood. The ventricles expand to pump blood into the lung. They then return to the center to start the next cycle of pumping. A Pvc Doctor begins in a different location in the Purkinje fibers are located in the left side of the heart.

When PVCs occur, they can make the heart pound or feel like it skipped a beat. If you've experienced only a few episodes, but no other symptoms, your doctor will probably not treat you. But if you have a number of PVCs, the window doctors doctor may recommend an electrocardiogram, also known as an ECG to determine your heartbeat over a 24-hour period. The doctor may also suggest wearing a Holter Monitor that records the heart's rhythm and count the number of PVCs.

People who have had a previous heart attack or suffer from cardiomyopathy -which alters the way the heart pumps blood - should take their PVCs seriously and consult a cardiologist about changes to their lifestyle. This includes avoiding alcohol, caffeine and smoking, managing stress and anxiety, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs, even if you don't have any other symptoms you should see a cardiologist. These irregular heartbeats could point to an issue with the structure of your heart or other health conditions, and over time, when they happen frequently enough, they can weaken the heart muscle. Most people with PVCs do not have any issues. They just want to be aware that the fluttering and racing heartbeats aren't normal.

Diagnosis

PVCs can feel like fluttering or skipped heartbeats, especially if they're intense or frequent. People who experience them frequently may feel weak. They can also occur with exercise, though many athletes who suffer from them don't have any problems with their heart or health. PVCs may show up in tests like an electrocardiogram or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to study the heart and observe how it's functioning.

A doctor can often tell if a patient has PVCs by looking at them and taking a medical history. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason, such as after an accident or surgery. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and can be used when there is a concern of cardiac disease.

If your cardiologist concludes that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are causing you discomfort or make you be anxious, avoiding alcohol, caffeine, and over the counter decongestants, and decreasing stress can help. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can reduce your episodes of PVCs. If your symptoms persist or are severe, speak with your physician about possible medications that can control them.

Treatment

If PVCs are rare or don't cause symptoms, they don't usually need treatment. If they occur frequently, your doctor might need to examine for heart conditions or recommend lifestyle adjustments. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips beats or has additional beats. PVCs are more frequent among those suffering from heart disease however, it's not clear what causes them. PVCs may increase in frequency as you age, and may occur more often during exercising.

If a patient experiences frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely perform an exercise stress test to determine if the additional heartbeats are related to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be conducted to determine other causes for the additional beats.

The majority of people with PVCs do not have any issues and can live an ordinary life. However, they can increase the risk of developing dangerous heart rhythm issues, especially if you have certain patterns of them. In some instances, this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

Regular exercise and a balanced diet will reduce your risk of developing PVCs. You should avoid foods that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. Sleep and stress are equally crucial. Some medicines may also increase the risk of developing PVCs. If you take any of these medicines it is essential that you follow the advice of your doctor about eating healthy exercising, as well as taking your medication.

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