Pacemaker-Induced Reverse Wenckebach
Report:Sinus rhythm 56 – 58/min 1 Reverse Wenckebach AV conduction 5 Demand pacemaker rhythm 60/min 1 Left atrial abnormality (LAA) 1 LVH with ST/T changes/incomplete LBBB 2 Comment:This may be the first reported case of reverse Wenckebach in a 12-le
Sensing but not Pacing
Report:Sinus rhythm 100/min 2 2:1 AV block 3 Left atrial abnormality (LAA) 1 Failure to pace in atrial-sensing pacemaker 3 Prolonged QT interval 0.56” 1 Comment:The unit is almost certainly a DDD one, with preserved atrial sensing but no ventricular
Reversible Katz-Wachtel Phenomenon
Report:Sinus rhythm 160/min Katz-Wachtel phenomenon â biventricular hypertrophy Comment:Here the evidence for RVH is confined to the upright T wave in V1 (abnormal from 4 days to 4 years) and for LVH to the sum of SV1 + RV5 voltages > 45 mm. However,
Dual Conduction and SVT
Report: Sinus rhythm Dual PR interval: 0.14â and 0.30â Comment: The two PR intervals alternated over periods of minutes, finally attracting the attention of the ICU night staff. Unfortunately, no spontaneous change was recorded. In the morning, I g
Sleeper With No ApnÅa
Report:Sinus arrhythmia Variable PR interval Second degree AV block, unspecified Single non-conducted P wave Comment:The block appears due to the respiratory variation of vagal tone and may have no more significance than a similar block induced in a h
