How a VC Can Affect Your Heart
Many people experience occasional PVCs with no problems. If they are frequent, PVCs may weaken your heart and increase your chance of suffering from heart failure.
The heart's rhythm is usually controlled by a group of nerve fibers situated in the upper right corner of your heart. glass doctor is called the sinoatrial node, or SA. Electrical signals travel from this node to the lower chambers of your heart or ventricles.
Causes
PVCs occur when the electrical impulse which normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles and causes an irregular heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beating or feels like it is fluttering. They may happen rarely and not cause any symptoms, or they may occur frequently enough to affect your daily life. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor may treat them with medication.
In most 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 true if the PVCs are caused by conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.
PVCs can trigger symptoms such as a feeling of your heart skipping an beat, or the feeling of your heart fluttering. You may also feel breathless. The fluttering could be more apparent when you exercise or have certain foods or drinks. PVCs are more prevalent in those suffering from chronic stress or anxiety. Certain drugs, like digoxin, amiodarone and cocaine, can also increase their risk.
If you have occasional PVCs your doctor may recommend lifestyle changes and medications. If they are a regular occurrence, you may have to stay clear of certain foods and beverages, such as caffeine and alcohol. You can also lower your stress levels by getting enough sleep and exercising.
If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. The treatment is typically effective in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib), an illness that can result in stroke. It is not common, but it could be life-threatening.
Symptoms
Premature ventricular contractions or PVCs may cause your heart to skip or flutter. These extra heartbeats can be harmless, however you might be advised to consult your physician if they are frequent or if you experience symptoms like dizziness, or fatigue.
The normal electrical signals start in the sinoatrial, located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. Then, the ventricles expand to push blood into your lungs, and then return to the heart to begin the next cycle of pumping. However, a PVC begins at a different spot that is separate from the bundle of fibers called the Purkinje fibers in the left-hand side of the heart.
When PVCs occur, they can make the heart beat or feel like it skipped a beat. If you experience a few episodes and no other symptoms, your doctor probably won't be able to 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. The doctor might also recommend wearing a Holter monitor that records the heart's rhythm over time, allowing you to see the number of PVCs you have.
If you've had a previous heart attack or have cardiomyopathy -an illness that affects how the heart pumps blood- must be aware of their PVCs and speak with an expert in cardiology about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.
Even if you don't experience any other signs it is still recommended to have PVCs checked by a cardiologist if they happen frequently. These heartbeats that are irregular 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 can weaken the heart muscle. The majority of people with PVCs don't experience any problems. They just want to be aware that the fluttering or skippy heartbeats aren't typical.
Diagnosis
PVCs can feel like fluttering or skipped heartbeats, especially if they're frequent or intense. People who experience them regularly may feel faint. They can also occur during exercising, but most athletes who experience them do not have any issues with their heart or health. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's functioning.
A doctor is often able to tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes it is possible that they only notice PVCs when examining patients for a different reason such as following an accident or a surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and could be utilized when there is a concern of a cardiac condition.
If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. However, if your symptoms are causing discomfort or cause you to feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress can aid. Regular exercise, being at a healthy weight and drinking enough water can decrease the likelihood of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medications that may be able to manage them.
Treatment
If PVCs are rare or do not cause symptoms, they do not usually need treatment. If you have them often and frequently, your doctor might want to check for other heart issues and recommend lifestyle changes or medication. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).
If you have PVCs, the electrical signal that causes your heartbeat is generated from a place other than the sinoatrial node (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 problems. PVCs may increase in frequency as we age and can occur more often during exercise.
A doctor should perform an ECG and an echocardiogram on a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to see whether the additional beats are a result of physical activity. To determine if there are other causes for the extra beats an invasive heart catheterization or a cardiac MRI could be conducted.
Most people who suffer from PVCs do not have any issues and can live an ordinary life. However, they may increase your risk of having dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases, that means that your heart muscle gets weaker and is having difficulty pumping blood through your body.
Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Sleep and stress are equally important. Some medicines can also increase your risk of PVCs. If you are taking one of these medicines, it's important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication.
In studies of patients with PVC burdens that are high (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was discovered. Some patients may require an organ transplant.
