How a VC Can Affect Your Heart
PVCs are common and may be experienced by a wide range of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The rhythm of your heart is controlled by a group of fibers that are located in the upper right corner of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel to lower heart chambers or ventricles.
Causes
PVCs are caused by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. Instead, the impulse is generated in another area of your heart called the ventricles and triggers an untimed beat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely and not cause any symptoms, but they can occur frequently enough to impact your quality of living. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medication.
For most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially true if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.
PVCs can trigger symptoms, such as a sensation of your heart skipping an beat, or the feeling of your heart fluttering. You may also feel breathless. The fluttering could be more evident when you exercise or consume certain foods or beverages. PVCs are more prevalent in those suffering from chronic stress or anxiety. Some medications, like digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs.
If you experience occasional PVCs Your doctor may suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor may recommend avoiding certain foods and drinks, like caffeine and alcohol. You can also take steps to reduce your stress, and make sure you get enough sleep and exercise.
If you have a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It destroys the cells that cause them. This procedure is performed by a specialist called 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 the risk of atrial fibrillation (AFib) which is an illness that can lead to stroke. It is not common, but it could be life-threatening.
Signs and symptoms
Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or flutter. These extra heartbeats are harmless, but you might want to consult your doctor when they occur frequently or if you are experiencing symptoms like dizziness, or fatigue.
Normally, electrical signals start in the sinoatrial node which is in the top right side of the heart. These signals descend to the lower chambers (or ventricles) which pump blood. The ventricles contract to propel the window doctor blood into your lungs, and then return to your heart to begin the next cycle of pumping. But a PVC starts in a different place that is separate from the window doctor near me bundle of fibers, known as the Purkinje fibers, in the lower left part of the heart.
When PVCs happen and the heart is affected, it may feel as if it's skipping a beat or pounding. If you only have just a few episodes and there are no other symptoms your cardiologist may not prescribe treatment. However, if you have large number of PVCs, the door doctor may recommend an electrocardiogram, also known as an ECG to gauge your heartbeat over the course of 24 hours. They may also suggest wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs.
If you've had a previous heart attack or have cardiomyopathy -which alters the way the heart pumps blood -- should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.
Even if you don't experience any other symptoms, you should still get PVCs checked by an expert in cardiology if they occur frequently. These extra heartbeats can indicate problems with the structure of your heart or other health issues and, over time, when they happen frequently enough, they may weaken the heart muscle. But most people with PVCs don't experience any problems. They simply want to know that the fluttering or racing heartbeats aren't normal.
Diagnosis
PVCs might feel like fluttering or skipped heartbeats, particularly when they're intense or frequent. People who get lots of them might feel like they're going to faint. Exercise can cause PVCs, but a lot of athletes who experience these symptoms do not have heart or health issues. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist might also use an echocardiogram that uses ultrasound to study the heart and determine how it's working.
A doctor is often able to tell the presence of PVCs by examining them and taking their medical history. But sometimes they might only be able to detect them when they examine the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitors can detect PVCs window and door doctor other arrhythmias. They may be used to identify cardiac problems when there is a concern.
If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are causing you discomfort or make you feel anxious, avoiding alcohol, caffeine and other over the counter decongestants, and decreasing stress can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your doctor about medications that could be able to manage the symptoms.
Treatment
If PVCs are rare or don't cause symptoms, they rarely require treatment. If they occur frequently, your doctor might need to examine for heart conditions or recommend lifestyle changes. You may also undergo an operation (called radiofrequency cathode ablation) to get rid them.
If you suffer from PVCs The electrical signal that causes your heartbeat begins somewhere outside of the sinoatrial node (SA node) in the top right corner of your heart. This can cause your heart to feel like it skips beats or has additional beats. PVCs are more frequent among those suffering from heart disease however, it's not clear what causes them. PVCs may increase in frequency as you age, and they may be more frequent during exercises.
If a patient is experiencing frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely perform an exercise stress test to determine if the additional heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other causes for the increased beats.
Most people who suffer from PVCs do not have any issues and can lead an ordinary life. They can increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases this means that the heart muscle gets weaker and it is more difficult to pump blood throughout your body.
A healthy, regular diet and regular exercise can help reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Stress and sleep are also important. Some medicines can also increase the risk of developing PVCs. So if you take one of these medications it is important to follow your doctor's instructions about a healthy diet, exercise and taking your medication.
In studies of patients suffering from Pvc Doctor burdens that are high (more than 20% of heartbeats), a higher rate arrhythmia-induced cardiac myopathy was discovered. This could lead to a need for a heart transplant in some individuals.
