Sick Sinus Syndrome: Repetitive Atrial Tachycardia
Report:Repetitive atrial tachycardia 180-230/min 5 Atrial and pacemaker escape beats 3 DDD pacemaker pacing at 66/min 2 Comment:This is an atrial tachycardia, with P waves not unlike sinus P waves in the frontal leads; the term SVT, while technically c
Controlling the Ventricular Rate: PVARP
Report:Atrial tachycardia 222/min (? slow flutter) with 2:1 block 4 LVH with ST/T changes (incomplete LBBB) 1 Atrial-sensing electronic pacemaker firing 111/min 1 Pseudofusion beats 4 Comment:The atrial tachycardia is somewhat discreet, but two atrial
Paced Bigeminy in PAT with Block
Report:Atrial tachycardia 146/min with block 2 100% paced atrial-sensing ventricular rhythm 97/min 3 Escape-capture bigeminy 5 Comment:This is a visually striking trace, with regular atrial tachycardia resulting in bigeminal paced ventricular rhythm. T
Overdrive of Atrial Tachycardia With Block
Report: Top: Atrial tachycardia 200/min 1 2:1 AV block 1 Pacemaker artefact 122/min 2 No capture 1 Second: Atrial pacing 250/min 3 Capture 0 Variable AV block 0.5 Third: Atrial pacing 80/min 0.5 1:1 conduction 0 Bottom: Sinus rhythm 68/min 1
Tricuspid Atresia
Report: Atrial tachycardia 150/min, variable block Ventriculophasic effect Left axis deviation â35o Nonspecific ST/T changes Prolonged QT interval Comment: The P waves are very broad and widely notched, like the sinus P waves (Fig 150a below). Both
LVH with Right Axis Deviation
Report: Atrial tachycardia (flutter) 208/min with 2:1 block Axis +90o Small voltage, limb leads Left ventricular hypertrophy with ST/T changes Comment: The rate of the flutter is very slow, presumably due to flecainide therapy; it was only reported as
PAT with Block: LBBB RSR' in V1
Report:Atrial tachycardia 216/min with 2:1 block. LBBB. Comment:The only indisputable part of the computer and the Cardiologistâs reports is tachycardia. The tachycardia could not be sinus tachycardia even if there was a 1:1 conduction: the morpholog
Concealed Non-Conduction
Report: Atrial tachycardia 186/min 3:1 AV block Comment: Can one really tell? The descent of some T waves is sharper than expected or shallowly notched; the same cycles also have a notch immediately following the end of the preceding QRS complex. Someth
Xylocaine & BBBB
Report:Atrial tachycardia, possibly sinus, 174/min 2:1 AV block Left bundle branch block Period of 1:1 conduction Comment:The exact doubling and then halving of the ventricular rate should have steered the CCU staff away from xylocaine. Broad complex
Concealed Non-Conduction
Report: Atrial tachycardia 186/min 3:1 AV block Comment: Can one really tell? The descent of some T waves is sharper than expected or shallowly notched; the same cycles also have a notch immediately following the end of the preceding QRS complex. Someth
