How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by a variety of people without causing any issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
A bundle of fibers located in the top right portion of your heart (the sinoatrial or SA node) typically controls your heart rhythm. Electrical signals travel to the ventricles or lower chambers of your heart.
Causes
PVCs happen when the electrical impulse that usually initiates your heartbeat at a point known as the sinus node (also known as the sinoatrial or SA Node) isn't. Instead, the impulse begins in another area of your heart, the ventricles, and causes an untimed beat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They may occur infrequently, causing no symptoms, but they can also happen frequently enough to affect your standard of life. Your doctor may prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.
In most people, PVCs are harmless and do not increase the risk of developing heart disease or other health issues. Regular PVCs however, could weaken the heart muscle over time. This is particularly relevant if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.
PVCs can trigger symptoms such as a feeling of your heart beating one beat, or even fluttering. You might also feel breathless. The fluttering may be more apparent when you exercise or eat or drink certain beverages or foods. People who suffer from chronic anxiety or stress can have more PVCs, and some drugs like amiodarone digoxin and cocaine can increase the risk of developing them.
If you have occasional PVCs your doctor might suggest lifestyle changes and medications. If they are a regular occurrence, you may have to avoid certain drinks and foods like caffeine and alcohol. You can also lower stress by taking enough rest and exercising.
If you have a lot of PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation, which eliminates the cells that cause PVCs. The procedure is carried out by a specialist, known as an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms, however it does not stop them from occurring in the future. In some cases, it can increase your risk of atrial fibrillation (AFib), which can cause stroke. This is rare but it could be life-threatening.
Symptoms
Premature ventricular contractions, also known as PVCs, can cause your heart seem to skip or flutter one beat. These extra heartbeats can be harmless, but you might be advised to consult your physician when they occur frequently or if you experience symptoms like dizziness, or fatigue.
Normally, electrical signals start at the sinoatrial junction, located in the upper right-hand side of the heart. They descend to the lower chambers (or ventricles) that pump blood. The ventricles contract to propel the blood into your lungs, and return to the heart and start the next cycle of pumping. A Pvc Doctor starts in a different place, the Purkinje fibres bundle at the bottom left of the heart.
When PVCs happen and the heart is affected, it may feel like it is skipping a beat or pounding. If you only have a few episodes, and no other symptoms are present the cardiologist will likely not prescribe treatment. If you've got a lot of PVCs the upvc doctor may recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over the course of 24 hours. He or she may also recommend wearing a Holter monitor that will track your heartbeat over time to determine the number of PVCs you have.
Anyone who has suffered an earlier heart attack or cardiomyopathy - an illness that affects heart's blood flow - should take their PVCs very seriously and consult an expert in cardiology about lifestyle modifications. This includes abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might prescribe medication to slow the double glazing doctor heartbeat like beta blockers.
If you have frequent PVCs, even if you do not have other symptoms you should see an expert in cardiology. These extra heartbeats can point to an issue with the structure of your heart or to other health conditions and, over time when they are frequent enough, they may weaken the window doctors heart muscle. But the majority of people suffering from PVCs don't experience any problems. They just want to know that the fluttering or skipping heartbeats aren't normal.
Diagnosis
PVCs might appear to be fluttering or skip heartbeats, particularly when they're intense or frequent. People who experience them often may feel weak. Exercise can trigger them, but many athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain 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 conducting a thorough examination and taking a medical history. However, sometimes they will only be able to detect them when they examine the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias and they might be used if there's any concern of cardiac disease.
If your cardiologist determines that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are troubling, or cause you to feel anxious, avoiding alcohol, caffeine and over-the counter decongestants, and the reduction of stress could aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can all aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your physician about the medications that could be able to control them.
Treatment
If PVCs are rare or do not cause symptoms, they do not usually need treatment. If you experience them frequently, your doctor may want to examine for other heart conditions and recommend lifestyle changes or medicine. You may also undergo a procedure (called radiofrequency cathode ablation) to get rid them.
When you have PVCs The electrical signal that causes your heartbeat starts somewhere different than the sinoatrial nerve (SA node) located in the upper right side of your heart. This could cause it to feel like your heart skips a beat or has extra beats. It's unclear what causes these, but they're more common in people who have other heart conditions. PVCs may increase in frequency as you age, and may be more frequent during exercise.
A physician should perform an ECG as well as an echocardiogram on a patient that suffers from frequent and painful PVCs to identify structural heart conditions. They may also perform an exercise stress test to see whether the extra beats are caused by physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be performed to find other causes for the extra beats.
The majority of people with PVCs don't experience any issues and can live a normal lifestyle. They can increase the risk of developing heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some cases this means that the heart muscle gets weaker and it is more difficult to pump blood throughout the body.
Regular exercise and a balanced diet will reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. Sleep and stress are also important. Certain medications can increase your risk for PVCs. If you're taking one of these drugs it's crucial to follow your doctor's instructions about a healthy diet, exercise and taking your medication.
Studies of patients who had a high burden of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require an organ transplant.
