How a VC Can Affect Your Heart
PVCs are common and can be experienced by many people without causing any issues. If they happen frequently, PVCs may weaken your heart window and door doctor increase your risk for heart failure.
The rhythm of your heart is controlled by a bundle of fibers located in the upper right corner of your heart. This is known as the sinoatrial node or SA. Electrical signals travel to the ventricles, or lower chambers of the heart.
Causes
PVCs occur when the electrical impulse which normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beating or feels fluttering. They may happen rarely and have no symptoms or they can occur frequently enough to interfere with your daily life. Your doctor may prescribe medicine when they occur frequently or cause dizziness, weakness or fatigue.
PVCs are generally harmless and do not increase the risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is especially when the PVCs are caused by conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.
The signs of PVCs include feeling like your heart beats faster or it flutters. You may feel breathless. The fluttering could be more evident when you exercise or have certain drinks or food items. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Some drugs, like digoxin, amiodarone and cocaine, may increase the risk.
If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medications. If they are a frequent occurrence, you may need to stay clear of certain foods and beverages like alcohol and caffeine. You can also lower your stress levels by getting enough sleep and working out.
If you have many PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, the window Doctors which eliminates the cells responsible for them. The procedure is carried out 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 some cases it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can lead to stroke. This isn't common however it could be life-threatening.
Signs and symptoms
Premature ventricular contractions, also known as PVCs, can cause your heart appear to flutter or skip a beat. These extra heartbeats are usually harmless, but it is important to talk to your doctor when you experience frequent episodes or other symptoms such as dizziness or weakness.
Normaly, electrical signals begin in the sinoatrial, located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles contract to force blood into the lungs. They return to the center to start the next cycle of pumping. A Pvc Doctor starts in a different location in the Purkinje fibres bundle in the bottom left of the heart.
When PVCs occur they can make the heart appear to be racing or pounding. If you have only a few episodes, but no other symptoms, the doctor will probably not treat you. If you have a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat over the course of 24 hours. They may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.
If you've had previously from a heart attack or have suffered from cardiomyopathy - an illness that affects method by which the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle modifications. These 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 you don't have any other indications, you should still get PVCs examined by an expert in cardiology if they occur often. These extra heartbeats may signal a problem with the structure of your lungs or heart, and if they happen often enough, it could weaken your heart muscle. Most people with PVCs do not have any problems. They simply want to be aware that the fluttering and racing heartbeats aren't normal.
Diagnosis
PVCs may appear to be fluttering or skip heartbeats, particularly when they're frequent or intense. People who experience a lot of them might feel like they're about to faint. They can also occur with exercising, but most athletes who suffer from them don't have issues with their health or heart. PVCs can show up on tests such as an electrocardiogram or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.
A doctor will usually be able to determine whether a patient has PVCs by examining them and taking their medical history. But sometimes they might only notice them while examining the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to detect heart disease if there is any concern.
If your cardiologist determines that your heart is structurally normal, reassurance is the only treatment needed. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine, and over the prescription decongestants, as well as the reduction of stress could help. Regular exercise, maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your physician about the medications that could help reduce these symptoms.
Treatment
If PVCs aren't causing symptoms or are not frequent they aren't usually in need of treatment. If they happen frequently, your doctor might be able to look for heart conditions or recommend lifestyle adjustments. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.
When you have PVCs The electrical signal that causes your heartbeat is generated from a place different than the sinoatrial nerve (SA node) in the top right corner of your heart. This can cause your heart to feel like it skips beats or has extra beats. It's unclear what causes these, but they're more frequent in those with other heart issues. PVCs may increase in frequency with age and might happen more often during exercising.
A doctor should perform an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to determine if there are structural heart problems. They may also perform an exercise stress test to determine whether the extra beats are caused by physical activity. To determine if there are other causes for the extra beatings the heart catheterization or a cardiac MRI is possible.
Most people who suffer from PVCs are not affected and can lead an ordinary life. However, they may increase your risk of having dangerous heart rhythm problems particularly if you have certain patterns of them. In some cases, this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.
Regular exercise and a healthy diet can lower the chances of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of caffeine and tobacco. Stress and sleep are also crucial. Certain medicines can also increase the risk of developing PVCs. If you are taking any of these medications it is essential that you follow your doctor's advice about eating healthy, exercising, and taking your medication.
In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This can lead to the need for a heart transplant in some patients.
