Ventricular heart rate on ekg strip

Ventricular tachycardia V-tach or VT is a type of regular, fast heart rate that arises from improper electrical activity in the ventricles of the heart. Ventricular tachycardia can occur due to coronary heart disease , aortic stenosis , cardiomyopathy , electrolyte problems , or a heart attack. In those who have a normal blood pressure and strong pulse , the antiarrhythmic medication procainamide may be used. While a few seconds may not result in problems, longer periods are dangerous. Ventricular tachycardia can occur due to coronary heart disease , aortic stenosis , cardiomyopathy , electrolyte problems e. The morphology of the tachycardia depends on its cause and the origin of the re-entry electrical circuit in the heart.

Ventricular tachycardia - Wikipedia

Electrocardiography is the process of producing an electrocardiogram ECG or EKG [a] , a recording — a graph of voltage versus time — of the electrical activity of the heart [4] using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle heartbeat. Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances such as atrial fibrillation and ventricular tachycardia , inadequate coronary artery blood flow such as myocardial ischemia and myocardial infarction , and electrolyte disturbances such as hypokalemia and hyperkalemia. In a conventional lead ECG, ten electrodes are placed on the patient's limbs and on the surface of the chest. The overall magnitude of the heart's electrical potential is then measured from twelve different angles "leads" and is recorded over a period of time usually ten seconds. In this way, the overall magnitude and direction of the heart's electrical depolarization is captured at each moment throughout the cardiac cycle. There are three main components to an ECG: the P wave , which represents the depolarization of the atria; the QRS complex , which represents the depolarization of the ventricles; and the T wave , which represents the repolarization of the ventricles.

Ventricular bigeminy

On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be.

Ventricular arrhythmias are abnormal heart rhythms originating in the ventricles that are the leading cause of sudden cardiac death. In this video, you will learn about ventricular arrhythmias and how to identify them on an EKG strip. In a normal heartbeat. It travels down the internodal pathways to the AV node 3.
