What Pvc Doctor Experts Want You To Learn
How a VC Can Affect Your Heart

PVCs are common and can be experienced by a variety of people without causing any problems. If they occur often, PVCs may weaken your heart and increase your risk of heart failure.

A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) typically controls your heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers or ventricles.

Causes


PVCs occur when the electrical impulse that typically initiates your heartbeat at a point known as the sinus node (also called the sinoatrial node or SA node) doesn't. Instead, the impulse is generated in another area of your heart called the ventricles and triggers an untimed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or is like it is fluttering. They can occur rarely without causing any symptoms, but they can be frequent enough to impact your quality of life. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and do not increase the risk of developing heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is particularly when the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure.

The symptoms of PVCs include feeling like your heart skips a beat or is fluttering, and you feel breathless. The fluttering can be more apparent when you exercise or consume certain foods or drinks. People who suffer from chronic anxiety or stress can have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the chance of developing them.

If you experience occasional PVCs Your doctor might suggest lifestyle changes and medication. If you have frequent PVCs, your doctor may suggest that you stay away from certain drinks and foods, such as caffeine and alcohol. You can also take steps to reduce your stress levels, and make sure you get enough sleep and exercise.

If you have many PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. This is done by a specialist known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms however, it doesn't prevent them from recurring in the future. In some cases it can increase your risk of atrial fibrillation (AFib) which could result in stroke. This isn't common however it could be life-threatening.

Signs and symptoms

Premature ventricular contracts, or PVCs can cause your heart to skip or flutter. These heartbeats can be harmless, however, you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, that pump blood. The ventricles expand to push the blood into the lungs. They then return to the center to start the next cycle of pumping. A PVC begins at a different spot that is the Purkinje fibers are located in the bottom left of the heart.

When PVCs occur, they cause the heart beat faster or feel like it skipped the beat. If you only have just a few episodes and no other symptoms are present the cardiologist will likely not treat you. However, if you have lot of PVCs, the doctor may recommend an electrocardiogram, or ECG, to measure your heartbeat over the course of 24 hours. The doctor may also suggest 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 prior heart attack or suffer from cardiomyopathy -- a condition that alters the way the heart pumps blood must be aware of their PVCs and talk to a cardiologist about changes to their lifestyle. Those include abstaining from alcohol, caffeine and smoking, reducing anxiety and stress and getting enough sleep. A cardiologist may prescribe beta blockers to slow down the heartbeat.

Even if there aren't any other signs however, you should have PVCs checked by an expert in cardiology if they occur frequently. These irregular heartbeats could be a sign of problems with the structure of your heart or other health conditions, and over time, if they occur often enough, they can weaken the heart muscle. Most people with PVCs do not have any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

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

A doctor is often able to tell whether a patient has PVCs by examining them and taking their medical history. However, sometimes they will not be aware of them until they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and could be utilized if there's any concern of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. However, if your symptoms are causing discomfort or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Getting regular exercise, staying at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms are persistent or extreme, consult your doctor about medication that could help manage them.

Treatment

If PVCs aren't causing symptoms or occur rarely they aren't usually in need of treatment. If they are frequent your doctor may need to examine for heart issues or suggest lifestyle changes. You might also get an operation to rid yourself of them (called radiofrequency catheter ablation).

If you have PVCs in your heart, the electrical signal which 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 your heart to feel like it skips beats or has additional beats. It's unclear what causes these symptoms, but they're common in people with other heart issues. PVCs may increase in frequency as you age, and could be more frequent during exercise.

If a patient experiences frequent and painful PVCs, a physician should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. They should also conduct an exercise stress test to determine whether the additional beats are a result of physical activity. To find out if there are other causes for the increased beats, a heart catheterization or a cardiac MRI can be performed.

The majority of people who suffer from PVCs do not experience any complications and can lead an ordinary life. They may increase your risk for dangerous heart rhythm disorders, especially if they occur in certain patterns. In certain cases, it means that your heart muscle gets weaker and has trouble pumping blood through your body.

Regular exercise and a healthy diet can lower your chances of developing PVCs. Avoid foods that are high in sodium and fat as well as restrict your intake of tobacco and caffeine. Sleep and stress are also crucial. Certain medications can increase your risk of PVCs. If you are taking any of these medications it is essential to follow your doctor's recommendations regarding eating a healthy diet, exercising, and taking your medication.

Studies of patients suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. the glass doctor may require an organ transplant.
