Respiratory T Wave Inversion(test)
Report: Sinus rhythm Respiratory T wave inversion Comment: Like in Case 117, the only danger to the patient is that her ECG strips may be taken seriously. It is more of a problem in 12-lead tracings, where only a few beats may be recorded in the right pre
Inferior Infarction and Left Anterior Hemiblock
Report:Sinus rhythm 78/min Left axis deviation â 72o Left anterior hemiblock Old inferior infarction Clockwise rotation (late transition) Comment:The LAHB is seen as inferior QS waves > 5 mm in depth, lack of secondary R waves in the inferior leads
Two Wrongs Making Two Rights!
Report: Sinus tachycardia 110/min Left bundle branch block Left axis deviation Runs of ventricular tachycardia 150 - 160/min AV dissociation Ventricular fusion beats Comment: This is from Schamroth himself: two wrongs sometimes make a right60. The t
Ventricular Flutter
Report: Top: Tachycardia 158/min of undetermined origin, possibly sinus Second strip: Tachycardia 165/min, as above, QRS broadening VEBs Ventricular flutter 250/min, with a torsade de pointes Third strip: Ventricular flutter 262/min Fourth strip:
Positive Concordant Precordial Pattern in VT
Report: Ventricular tachycardia 175/min Comment: The diagnosis depends on: - concordant (positive) precordial pattern - monophasic R wave in V1 - AV dissociation - known pre-existing LBBB62 Below (Fig 67a) is his 12-lead ECG 3 hours earlier, in mult
Acute Infarction with Pre-existing LBBB
Report:Sinus rhythm 60/min Left atrial abnormality (LAA) Left bundle branch block Acute inferior & anterior infarction Comment:The diagnosis was based on new and marked ST segment elevation in the inferior leads and V3 as well as concordant T inversio
Left Main Coronary Artery Pattern
Report:Sinus rhythm 90/min Probable left ventricular hypertrophy ST/T changes c/w infarction/ischæmia Main left coronary artery lesion pattern Comment:Diffuse ST segment depression â sparing, oddly enough, in this example, aVL â connotes extensiv
Failure to Pace
Report:Sinus rhythm approximately 75/min 1 AV dissociation 3 Pacemaker rhythm 88/min 4 Intermittent failure to capture (pace) 2 Comment:Large pacemaker spikes march regularly throughout, but the 10th spike is not followed by a QRS. The morphology of
Pacemaker-Ventricular 2:1 Block
Report:Sinus rhythm 94/min 1 Atrial-sensing ventricular pacemaker rhythm 4 AV block (unspecified) 1 2:1 pacemaker-ventricular block 4 Comment:T wave’s more trouble than it’s worth. One cannot be sure whether we are dealing with sinus rhythm 94/min or
Agonal Pacemaker Rhythm
Report: Pacemaker rhythm 80/min 4 Broad pacemaker complexes 0.36” suggest hyperkalæmia or agonal rhythm 6 Comment: It was the latter – agonal rhythm. I rang the patient’s physician who told me the patient had by then been allowed to die, in cardiogenic
