atrial flutter Cardiology Rapid, well organized contraction of the atrium at a rate of 250-350 beats/min; at atrial beats < 200/min, the ventricles can respond in a 1:1 fashion–at higher atrial rates, they respond with a 2:1, 3:1, or 4:1 block EKG Sawtooth waves and evidence of continued electric activity, best seen in II, III, aV_f or V₁ Etiology Paroxysmal AF may occur in normal hearts; chronic–persistent AF is often associated with underlying heart disease–eg, rheumatic or ischemic heart disease, cardiomyopathy, or PTE, mitral or tricuspid stenosis or regurgitation, thyrotoxicosis, alcoholism, pericarditis Clinical Asymptomatic, flutter in jugular venous pulse Management Synchronous DC–direct current cardioversion at low energy–
< 50 joules; CCBs–eg, verapamil and diltiazem
