A premature beat that originates in the atria in an area other than the sinus node followed by a normal ventricular response is sometimes referred to as premature atrial contractions.
A ventricle is one in every one of the large chambers closer to the bottom of the coronary heart that acquires and expels blood towards the peripheral beds inside the body and lungs. The blood pumped by using a ventricle is furnished through an atrium, an adjoining chamber in the top coronary heart that is smaller than a ventricle.
The decreased chambers are the left ventricle and proper ventricle. The proper ventricle pumps blood from your heart and into your lungs, which add oxygen and do away with carbon dioxide earlier than the blood reenters your heart. The left ventricle is the remaining chamber blood flows via before being pumped out to your entire body.
Ventricular tachycardia occurs because of a problem with the coronary heart's electric impulses. The situation may additionally broaden as a complication of a heart assault or may arise in human beings with certain situations, which include valvular heart disease.
