Where are Beta 1 receptors found? - Correct Answer Heart and Kidneys Stimulation of Beta 1 receptors result in an increase of what? - Correct Answer Heart: Inotropy, Chronotropy, Dromotropy Kidneys: Renin-Angiotensin-Aldosterone System = Vasoconstriction = Increase blood pressure Which node is located at the junction of the superior vena cava and the right atrium, is typically supplied by the Right Coronary artery, and fires at a rate of 60-100 bpm. - Correct Answer SA Node Atrial depolarization characterized by smooth, round, upright deflection less than 0.11 secs long and less than 2.5mm tall is referred to as what on the ECG? - Correct Answer P wave Carvedilol (Coreg) Metropolol (Lopressor) Atenolol (Tenormin) Propranolol (Inderal) Bisoprolol (Zebeta) Acebutolol (Sectral) Comolol (Brevibloc) - Correct Answer Beta Blockers - used for blood pressure and cardiac problems Epinephrine Norepinephrine Vasopressin Dopamine Phenylephrine Dobutamine - Correct Answer Vasopressors The middle of phase 3 to beginning of phase 4 in the cardiac cycle where cardiac cells are partially refractory and partially repolarized and certain cells can be depolarized in response to electrical stimulus. - Correct Answer Relative Refractory Period (Partial flush of the toilet) Starlings Law - Correct Answer When end diastolic volume increases, stroke volume increases as well. (When more blood is in the ventricles, the cardiac muscle stretches like rubber band and creates more forceful contraction)
