The condition of irregular quivering of the atria and rapid ventricular heartbeat is atrial fibrillation, or a-fib. While serious, a-fib is not immediately life threatening.
VT=V Tach=Ventricular tachycardia
Ventricular tachycardia
ventricular tachycardia
A tachyarrhthmia is an abnormal and rapid heart rhythm. Tachycardia is a broader term that refers to a rapid heart rate.
Ventricular tachycardia is a potentially fatal condition of rapid heart beat originating from electrical signals from the ventricles.
Ventricular tachycardia is the term for rapid heart rate starting in the ventricles. Any resting pulse rate over 100 in an adult is defined as tachycardia.
Fibrillation
An abnormal, rapid heart rhythm, due to an extra pathway for the electrical impulses to travel from the atria to the ventricles.
Atrial flutter-- Rapid, inefficient contraction of the upper chamber of the heart.
Ventricular fibrillation is the term for rapid irregular contractions of the ventricles. Because the contractions are unsynchronized and random, the ventricles do not pump effectively. The patient may have no palpable pulse, and the condition can be fatal.
rapid and uncoordinated contractions of the atria or ventricles. This condition is known as fibrillation. When the atrial impulse fails to reach the ventricle, a condition known as heart block results.
Cardiomegaly is the abnormal enlargement of the heart that is frequently associated with heart failure when the heart enlarges in an effort to compensate for the loss of its pumping ability (cardio means heart, and -mealy means abnormal enlargement). Tachycardia is an abnormally rapid resting heart rate (tachy- means rapid, card means heart, and -ia means abnormal condition). This term is usually applied to rates greater than 100 beats per minute. Tachycardia is the opposite of bradycardia. Paroxysmal atrial tachycardia, also known as PAT, is an episode that begins and ends abruptly during which there are very rapid and regular heartbeats that originate in the atrium. PAT is caused by an abnormality in the body's electrical system. Paroxysmal means pertaining to sudden occurrence. Ventricular tachycardia, also known as V tach, a very rapid heart beat that begins within the ventricles. This condition is potentially fatal because the heart is beating so rapidly that is is unable to adequately pump blood through the body. For some patients, this conditon can be controlled with an implantable cardioverter defibrillater.
The nervous system controls heart rate and respiratory rate. It may be influenced by the endocrine system as well. A rapid heart and breathing rate are typical results of activation of the sympathetic nervous system.
Ventricular tachycardia, VT or V-Tach is an extremely rapid heartbeat that starts in the ventricles.
Very rapid contractions or twitching of small muscle fibers in the heart often need to be stopped. A mechanism that does this is called a defibrillator. The act itself is call a defibrillation. Many times the top chambers of the heart go into fibrillation and are not as severe as the ones that occur in the bottom chambers called the ventricles. These must be stopped as quickly as possible.
Fibrillation is the medical term meaning rapid uncoordinated shuddering of the heart.
The combustion reaction begins with the rapid combination of a fuel and oxygen. This produces heat and light (fire).
