How a VC Can Affect Your Heart

PVCs are common and can be experienced by many people with no cause for concern. If they are frequent, PVCs may weaken your heart and increase the risk for heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial, or SA, node) typically controls the heart's rhythm. Electrical signals travel to the lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse that typically begins your heartbeat in a part known as the sinus node (also called the sinoatrial or SA Node) isn't. Instead, the impulse begins in a different part 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 skipped a beating or feels like it is fluttering. They can occur rarely without causing any symptoms, but they may occur frequently enough to affect your quality of life. Your doctor may prescribe medication if they are frequent or cause weakness, dizziness or fatigue.

PVCs are generally harmless and do not increase the risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially when the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

The symptoms of PVCs include feeling like your heart beats slower or flutters, and you may feel exhausted. The fluttering could be more noticeable when you exercise or have certain drinks or foods. PVCs are more common in people with chronic stress or anxiety. Certain medications, like digoxin, amiodarone or cocaine, may increase their risk.

If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and Soundproof Window Repair medications. If they are a frequent occurrence, you may have to stay clear of certain drinks and foods, such as alcohol and caffeine. You can also lower your stress by getting enough sleep and working out.

If you're experiencing a lot of PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation, which destroys cells that cause PVCs. This procedure is performed by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but does not prevent them from becoming recurring in the future. In certain cases it may increase your risk of atrial fibrillation (AFib) which could cause stroke. It's not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, may make your heart appear to skip or flutter one beat. These heartbeats can be harmless, but you should talk to your doctor if you have frequent episodes or signs like dizziness or weakness.

The normal electrical signals start in the sinoatrial, located in the upper right-hand part of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. Then, the ventricles contract to propel the blood into the lungs, and return to the heart and start the next pumping cycle. But a PVC begins in a different location and is located in the bundle of fibers called the Purkinje fibers, in the lower left part of the heart.

When PVCs occur, they cause the heart pound or feel as if it skipped the beat. If you've experienced a few episodes and no other symptoms, your cardiologist probably won't treat you. If you've got a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. He or she might also recommend wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs.

If you've had previously from a heart attack or cardiomyopathy - an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle modifications. This includes cutting down on caffeine, alcohol and smoking, reducing anxiety and stress, and Childproof window repair getting enough rest. A cardiologist can prescribe medications to slow heartbeat, like a beta blocker.

Even if there aren't any other signs however, you should have PVCs checked by an expert in cardiology if they occur often. These irregular heartbeats could be a sign of a problem with the structure of your heart or other health conditions, and over time, if they occur often enough, they may weaken the heart muscle. The majority of people with PVCs don't experience any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience a lot of them might feel like they're going to faint. They can also occur with exercising, but most athletes who experience them don't have any problems with their heart or health. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.

A doctor can often tell the presence of PVCs by examining them and taking their medical history. Sometimes it is possible that they only notice PVCs when examining patients for a different reason, like following an accident or surgery. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They are able to detect cardiac disease in the event of any concern.

If your cardiologist determines that your heart is structurally normal, reassurance will be the only treatment needed. However, if your symptoms are troubling or cause you to feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress may help. Regular exercise and maintaining a healthy weight and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms are persistent or severe, speak to your physician about the medications that could help reduce them.

Treatment

If PVCs do not cause any symptoms or happen rarely, they usually don't need treatment. If they happen frequently, your doctor might want to check for heart problems or suggest lifestyle modifications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart, the electrical signal which causes your heartbeat begins somewhere different than the sinoatrial (SA) node that is located in the upper right corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. It's unclear what causes them, but they're more common in people who have other heart issues. PVCs may increase in frequency as you age, and could be more frequent during exercises.

A physician should perform an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to identify structural heart conditions. The doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are caused by physical exercise. A heart catheterization or apartment window Repair cardiac MRI or nuclear perfusion studies can be done to look for other causes of the additional beats.

Most people who suffer from PVCs do not suffer from any issues and can live a normal lifestyle. They may increase the risk of heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In certain cases, it means the heart muscle gets weaker and has trouble pumping blood throughout your body.

A healthy, regular diet and plenty of exercise can reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. It is also important to get enough rest and manage stress. Certain medications can increase the risk of developing PVCs. If you are taking any of these medicines, it is important to follow the advice of your doctor about eating healthy, exercising, and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. This can result in the need for a heart transplant in a few individuals.
