How a VC Can Affect Your Heart

PVCs are common and may be experienced by many people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.

The rhythm of your heart is 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 from this node to the lower chambers of your heart or ventricles.

Causes

PVCs are caused when the electrical impulse which normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually begins in the ventricles, causing an irregular heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beat 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 living. If they happen frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medicine.

For the majority of people, PVCs are harmless and do not increase the risk of heart disease or other health problems. Over time, frequent PVCs can weaken the heart muscle. This is particularly relevant if they are triggered by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

The symptoms of PVCs include feeling like your heart beats slower or is fluttering, and you feel exhausted. The fluttering may be more evident when you exercise or have certain foods or drinks. PVCs are more common in those suffering from chronic stress or anxiety. Some medications, such as digoxin, amiodarone or cocaine, can increase the risk.

If you experience occasional PVCs Your doctor might recommend lifestyle changes and medicines. If they are a regular occurrence, you may need to stay clear of certain drinks and foods like alcohol and caffeine. You can also take steps to reduce your stress 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. This is done by a specialist known as an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some cases, it can increase your risk of having atrial fibrillation (AFib), which can lead to a stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are harmless, but you might need to see your doctor in the event of frequent heartbeats or if you experience symptoms like dizziness, or fatigue.

Normally, electrical signals begin at the sinoatrial junction, located in the top right portion of the heart. These signals move down to the lower chambers (or ventricles) that pump blood. The ventricles expand to push blood into the lungs, and then return to the heart to begin the next pumping cycle. However, a pvc doctor begins in a different location that is separate from the bundle of fibers, known as the Purkinje fibers in the lower left part of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped a beat. If you have only a few episodes, but no other symptoms, your doctor probably won't be able to treat you. If you've got a lot of PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. The doctor may also recommend wearing a Holter Monitor that records the double glazing doctor heart's rhythm and count the number of PVCs.

Anyone who has suffered a heart attack in the past or have cardiomyopathy -which alters the way the heart pumps blood - should take their PVCs seriously and speak with a cardiologist about changes to their lifestyle. This includes the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might prescribe medications 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 a cardiologist. These extra heartbeats can indicate problems with the structure of your heart or other health issues and, over time, when they are frequent enough, they can weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They simply want to be aware that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that flutter, especially if they are frequent and intense. People who experience a lot of them may feel they're about to faint. They can also occur during training, even though many athletes who experience them do not have any issues in their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

Often, a doctor will be able to tell whether someone has PVCs from a patient's history and physical examination. Sometimes it is possible that they only notice PVCs when examining a patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition.

If your cardiologist finds that your heart's structure is normal, reassurance will be the only treatment needed. However, if your symptoms are causing discomfort or cause you to feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Regular exercise, being at a healthy weight and drinking enough water can also decrease the likelihood of PVCs. If your symptoms continue or are severe, talk with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs do not cause any symptoms or happen rarely, they usually don't need treatment. If they occur frequently your window doctors near me & door doctor (view it now) may want to check for heart issues or suggest lifestyle changes. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or has extra beats. PVCs are more prevalent among people with heart problems, but it's not known the reason behind them. PVCs can become more frequent as you age, and might occur more frequently during exercises.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also likely perform an exercise stress test to determine if the increased heartbeats are related to physical activity. To find out if there are other causes for the increased beats the heart catheterization or a cardiac MRI could be conducted.

Most people who suffer from PVCs have no complications and live the normal life. But they can increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases, this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout the body.

A regular, healthy diet and plenty of exercise can reduce the chances of developing PVCs. Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco. Stress and sleep are also important. Certain medications can increase your risk for PVCs. If you take any of these medicines it is crucial that you follow the advice of your doctor about eating healthy and exercising as well as taking your medication.

Studies of patients who had a high burden 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 the need for a transplant in a few people.
