As a rule, premature ear contractions have no clear cause and no health risk. In most cases, premature ear twitches are not a sign of heart disease and simply occur naturally. Premature ventricular contractions (CSPs) are additional heartbeats that begin in one of the two lower pumping chambers (ventricles) of your heart. These extra beats disrupt your normal heartbeat and sometimes make you feel a floating or jumping beat in your chest. Rarely, premature contractions can be caused by a disease or injury to the heart. If your doctor suspects this possibility, he or she may suggest tests to monitor your heart function. Premature ventricular contractions are common – they occur in many people. They are also called: Symptoms of PVC include a floating or flip-flopping sensation in the chest, a throbbing or jumping heartbeat, skipped beats and palpitations, or increased awareness of your heart rate. A patient with SYMPTOMS of PVC who sees a heart specialist undergoes an ECG, the standard test used to diagnose PVC. It is relatively inexpensive, non-invasive and accurate.

A Holter monitor, a portable ECG that allows 24 or 48 hours of continuous recording, can be used for patients who suffer from PVC at least once a day. Information from a Holter monitor is very useful for determining the frequency of PVC and correlating symptoms such as fainting or dizziness with arrhythmia. The reasons are not always clear. Certain triggers, heart disease, or changes in the body can make ventricle cells electrically unstable. Heart disease or scarring can also lead to wrong direction of electrical impulses. They are the most common reason for arrhythmia or irregular heartbeat. Premature ventricular contractions (PMCs) are abnormal additional heartbeats that begin in the lower ventricles or pumping chambers and disrupt your normal heartbeat, sometimes making you feel a skipped beat or palpitations. PVCs – also called premature ventricular complexes, premature ventricular beats and extrasystoles – are very common and generally harmless. Premature ventricular contractions (PVCs) are a type of abnormal heart rhythm. Its heart has 4 chambers: 2 upper atria and 2 lower ventricles. Usually, a special group of cells starts the signal for your heart rate. These cells are located in the sinus node (AS) of the right atrium.

The signal moves quickly through the conductive system of your heart. It moves to the left and right ventricles. As it moves, the signal triggers the contraction of nearby parts of your heart. This allows your heart to squeeze in a coordinated way. PVC can be difficult to diagnose because it occurs at unpredictable intervals. In most cases, PVCs are difficult for the doctor to detect during a routine physical examination unless the patient has any signs of structural heart problems during the examination. In people without known heart disease, PVCs are often discovered by chance during a routine electrocardiogram (ECG). In patients with known heart disease, PVC can be detected in other diagnostic tests for this condition. With a PVC, the signal to start the heartbeat comes from one of the ventricles instead. This signal is premature, which means that it occurs before the SA node has had a chance to trigger. The signal travels through the rest of your heart and can cause a different heartbeat than normal.

Depending on when the premature beat occurs, you may not feel anything at all, a skipped heartbeat, drowsiness, shortness of breath, or even chest pain. Experts aren`t sure what causes the extra beat known as PVC. They tend to happen for no real reason, but certain triggers and health problems may play a role. These include: Most PVC is rare and benign. Common PVCs can increase the risk of developing other, more serious cardiac arrhythmias. People with frequent PVC who have heart disease, structural abnormalities in the heart, or a previous heart attack have a higher risk of death. If your doctor determines that you have a condition related to premature heartbeat, work together to create a treatment plan. .
