Symptomatic Bigeminy Due to Trigeminy
Report: Sinus rhythm 80/min 1 Blocked SVEBs, trigeminal 8 A-sensing ventricular pacing throughout 1 Comment: Not surprisingly, the pacemaker was blamed. It was programmed to pace at 60/min, with a sleep mode of 50/min during night hours. There was no
Left Ventricular Epicardial Pacemaker
Report:AV pacemaker rhythm 81/min 2 Unusual axis ? left ventricular electrode 8 Comment:The pacemaker has 100% atrial and ventricular capture. The unusual RAD in the frontal plane and RV1 suggest a left ventricular electrode. This may be deliberate or
Atrial Pacemaker Rhythm: Wenckebach Periods
Report:Dowling Dennis Raymond 55 15/4/00 106504Atrial pacemaker rhythm 89/min 2 Second degree AV block, Möbitz 1 5 Left ventricular hypertrophy with ST/T changes 2 Probable old inferior infarction 3 Comment:The spike-to-R interval (equivalent of PR o
Unusual Mechanism of Escape-Capture Bigeminy
Report: Sinus rhythm 0.5 SVEBs, blocked, in (atrial) trigeminy 2 AV sequential pacemaker, atrial-sensing (probably DDD) 0.5 Failure to sense SVEBs 4 Atrial-paced escape beats 0.5 Ventricular bigeminy (atrial trigeminy!) 2 Nonspecific T wave changes
LVH with ST/T Changes
Report:Sinus bradycardia 49/min Left atrial abnormality Left ventricular hypertrophy with ST/T changes Comment:There are typical repolarisation changes in all the leads; the voltage criteria offer an embarrassment of riches. The LAA is part of LVH cri
Katz-Wachtel Phenomenon
Report:Sinus rhythm 128/min Right atrial abnormality Right ventricular hypertrophy Left ventricular hypertrophy Comment:The voltages are the very large (91mm QRS V4, pure R 12mm V1). Katz-Wachtel phenomenon denotes the large, relatively equiphasic, mi
Non-Q Infarction
Report:Sinus rhythm ST/T changes consistent with infarction/ischæmia Poor R wave progression Comment:This is the same patient whose stage of illusion is shown on the preceding page. Now, 24 hours later, the T waves have âflippedâ and the cardiac
Left Atrial Abnormality
Report: Sinus rhythm Left atrial abnormality First degree AV block PR 0.36â Normal axis Left bundle branch block QRS 0.125â Comment: The P waves are 0.12â (3 mm) long. Their P-terminal force (PTF) in lead V1 is well over 1 mm deep and 1 mm l
Rigor Mortis!
Report: Asystole. Comment: This is one of several dead patientsâ ECGs I encountered during my three years in the United States. Presumably itâs their passion for âdocumentationâ that leads (some) Americans to take ECGs on (some) cadavers, maybe t
Hypokalæmia: Prominent TU Waves
Report:Sinus rhythm 73/min Prolonged QT interval 0.46â QTc 0.50â Comment:It is practically impossible to discern an overlapping U wave here; there is a hint in 3 and aVF. Her potassium level was 2.9 mEq/L; other electrolytes were normal, as was he
