endocarditis - inflammation of the endocardium (the lining of the cavities of the heart and connective tissue bed) hypertension - greater then 140/90 diuretics - an agent that promotes excretion of urine digitalis - a pharmacologic agent used to treat congestive heart failure, atrial fibrillation, atrial flutter, and paroxysmal tachycardia of the atria ischemia - deficiency of blood to a body part due to functional constriction or obstruction of a blood vessel p wave - a wave on ekg that represents contraction of atria t wave - represents repolarization of the ventricles qrs complex - reflects activity that produces ventricular contraction ectopic foci - a displaced central point of origin for a cardiac dysrhythmia supraventricular foci - central points of origin of dysthymias, which are located above the level of the ventricles in the atria ventricular foci - a displaced point of origin for a dysthymia that is in the ventricles arrest rhythms - cardiac rhythms in which there is cardiac arrest. some arrest rhythms such as pulseless ventricular tachycardia are accompanied by a rhythm display, but there is no contraction compensatory pause - a long beat that compensates for a shorter beat which contains either an atrial or ventricular premature contraction supraventricular tachycardia - rate of 150-250 BMP, narrow QRS complex paroxysmal supraventricular tachycardia - sudden attacks of rapid heartbeats atrial fibrillation - irregular and rapid ventricular rate atrial flutter - atrial contractions are regular but rapid, 200-320 BPM junctional rhythms - cardiac dysrhythmia in which the ectopic pacemaker is in the area of the AV junction premature ventricular contractions (PVC) - premature contraction of the heart that is independent of the normal rhythm and arises in response to an impulse in the ventricle
