Tachycardia is a condition characterized by (1) heart-rate decreases from the normal (2) heart- rate increases from the normal (3) heart-beat stops (4) heart fails to pump

1 Answer

Answer :

(2) heart- rate increases from the normal Explanation: Tachycardia is a heart rate that exceeds the nor-mal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. A healthy adult heart normally beats 60 to 100 times a minute when a person is at rest. Tachycardia occurs when an abnormality in the heart produces rapid electrical signals.

Which of the following terms is used to describe a tachycardia characterized by abrupt onset, abrupt cessation, and a QRS of normal duration? a) Paroxysmal atrial tachycardia PAT is often caused by a conduction problem in the AV node and is now called AV nodal reentry tachycardia. b) Sinus tachycardia Sinus tachycardia occurs when the sinus node regularly creates an impulse at a faster-than-normal rate. c) Atrial flutter Atrial flutter occurs in the atrium and creates an atrial rate between 250-400 times per minute. d) Atrial fibrillation Atrial fibrillation causes a rapid, disorganized, and uncoordinated twitching of atrial musculature.

Premature ventricular contractions are considered precursors of ventricular tachycardia when they a) occur at a rate of more than six per minute. When PVCs occur at a rate of more than six per minute they indicate increasing ventricular irritability and are considered forerunners of ventricular tachycardia (VT). b) occur during the QRS complex. PVCs are dangerous when they occur on the T wave. c) have the same shape. PVCs are dangerous when they are multifocal (have different shapes). d) are paired with a normal beat. A PVC that is paired with a normal beat is termed bigeminy.
