Termination of SVT: Pacemaker Escape
Report:Supraventricular tachycardia 165/min 1 Electrical alternans 2 Termination of paroxysm 0 Atrial escape beat (fusion) 2 Pacemaker escape beat 1 Sinus beat (fusion) 2 VEB (last complex) 1 Nonspecific ST/T changes, possible LVH (R2 = 15 mm) 1
Pacemaker Tachycardia with Spike Alternans
Report:AV sequential pacemaker tachycardia 120/min 8 Pacemaker spike alternans 2 Comment:The patient refused to stay in Casualty and went home. He returned several days later, when his pacemaker was “interrogated”. No malfunction was found in this DDDR
Inferior MI Reperfusion â Fascicular VT
Report:Ventricular tachycardia 156/min/min Probable inferior infarction Comment:The rhythm was sufficiently irregular for the computer to classify it as AF with borderline IVCD. It becomes more regular, however, just after the middle of the trace and en
Pericardial Tamponade: Electrical Alternans
Report:Sinus tachycardia 111/min Small voltage Electrical alternans Comment:Alternate QRS complexes vary in size, in this case due to the heart swinging in the pericardial sac. There is no mechanical counterpart, but there may be alternation of the hea
Sudden Death During Holter Monitoring
Report: Supraventricular and ventricular bigeminy Prolonged QT interval (0.64â) Multiform, probably torsade de pointes, ventricular tachycardia Comment: This patient was on digoxin and quinidine. The final (and fatal) paroxysm is initiated by a late
True Alternans in Cardiac Tamponade
Report:Sinus tachycardia 126 - 132/min Electrical alternans Comment:By definition, there must be no change in rhythm or conduction for alternans to be diagnosed. In this case, the mechanism is the "swinging" of the heart, pendulum-like, within the peric
Electrical Alternans at 300/min
Report:Supraventricular tachycardia 300/min Electrical alternans Comment:At fast rates, electrical alternans has no connotation of cardiac failure. It can be quite transient: below (Fig 73a) is a trace at only slightly slower rate, without alternans. T
IVCD & ST/T Alternans: Tricyclic Overdose
Report:Broad complex tachycardia of uncertain origin QRS 0.28â Probable atrial ? sinus tachycardia ST/T alternans Comment: The patient was in coma, but not fitting; in shock, but not circulatory collapse; the QRS was well over 0.16â, but there wer
Alternating Retrograde Conduction in Accelerated Junctional Rhythm
Report:Accelerated junctional rhythm 92/min 2:1 retrograde block Right axis deviation Lateral infarction, acute or recent Borderline small voltage in frontal leads Electrical alternans V1 Comment:One would be tempted to say that this trace is an exa
