12 lead ECG - electrodes are placed on the arms and legs and on the chest around the heart. 1st degree AV block - PR interval is greater than 0.20 May be caused by ischemia or digitalis Treated with atropine 2nd degree AV block - Irregular rhythm, normal P waves, QRS complex is missing. Treated with atropine or a pacemaker 3rd degree AV block - Atrial rate greater than 60/min, ventricular rate less than 40/min PR interval cannot be determined, QRS complex will be widened. Treated with pa...

1ST DEGREE AV BLOCK - Answer-THE P WAVE PRECEDES EACH QRS COMPLEX BUT THE PR INTERVAL IS .0.2 SECS. 22 PREMATURE ATRIAL CONTRACTIONS - Answer-THERE ARE PREMATURE AND ABNORMALLY SHAPED P WAVES. THE PR INTERVAL IS TYPICALLY WITHIN NORMAL LIMITS, BUT MAY BE SHORT OR SLIGHTLY PROLONGED. THE QRS COMPLEX IS USUALLY WITHIN NORMAL LIMITS AND NORMAL CONFIGURATION 2ND DEGREE AV BLOCK MOBITZ 1 (WENCKEBACH) - Answer-DISEASED TISSUES OF THE AV NODE CONDUCT EACH IMPULSE EARLIER IN THE REFRACTORY PERI...
