The Frailty of Lead 2 Monitoring
Report:Sinus rhythm 78/min VEBs in bigeminy Right bundle branch block Small voltage Possible old anterior infarction Comment:Leads V1-5 clearly distinguish between the ectopic ventricular and the sinus RBBB conduction. Lead 2 performs, as usual, badl
VT: R in V1: Sharp Upstroke and Slurred Descent
Report:Ventricular tachycardia 186/min Comment:The qR in V1 (and V2) has a sharp ascent and slower descent, an equivalent of the rabbit-ear sign of VT112. In the frontal plane, the QRS axis is in no-manâs land at about +260o. There is little reason to
Thioridazine Overdose
Report:Junctional/sinus rhythm VEB, dimorphic couplet Non-sustained ventricular tachycardia (torsade de pointes) Comment:The torsades were very frequent, but the 12-lead ECG did not catch the best of them. Nevertheless, the one shown here is reasonably
Sotalol Sensitivity
Report:Atrial ?junctional bradycardia 42/min VEB Long QTc 0.54â Comment:The first beat is distorted by movement artefact: its repolarisation in L1 and L3 and preserved QRS shape in simultaneous L2 distinguish it from a VEB. The striking abnormality
Interpolation in Alternate Cycles
Report:Sinus rhythm 51/min VEBs, interpolated in alternate cycles Trigeminy Non-specific ST/T changes Comment:The VEBs are typical, with nonsense axis and qR morphology in V1; their concealed retrograde conduction114, prolonging the PR intervals of th
Fascicular Ventricular Tachycardia
Report:Ventricular tachycardia 141/min Comment:The complexes are between 0.10 and 0.12â in duration (even narrower than in Case 11), with left axis deviation â40o. The morphology is that of incomplete LBBB except for the all-important lead V1, where
Ventricular Escape Beat
Report: Sinus rhythm 70/min SVEBs VEB Left atrial abnormality (LAA) Left anterior hemiblock Right bundle branch block Prolonged QT interval (QTc 0.50â) Nonspecific ST/T changes Possible LVH (R in aVL >15mm, R1 + S3 > 27mm) Probable anterosepta
VEB: the Compensatory Pause
Report:Sinus rhythm 62/min First degree AV block (PR 0.22â) VEB Left bundle branch block Comment:The P waves are sharply etched in V1 and the one blocked by the VEB is seen quite clearly. There is no need to measure the compensatory pause containing
VEBs: Long Compensatory Pauses
Report:Sinus rhythm 97/min VEBs Right bundle branch block Probable old inferior infarction Comment:The pauses containing the VEBs are obviously longer than two sinus cycles. This admits only one explanation â the VEBs have been conducted retrogradel
Rosenbaum Extrasystoles
Report:Sinus rhythm VEBs in bigeminy Borderline ST segment depression Comment:The VEBs look, at first, quite similar to sinus beats in the V1 rhythm strip. Two things show they are VEBs: the small but 0.04â thick initial R wave and the late S wave na
