Arrhythmias The Disorders of Cardiac Rhythm was enthusiastically received on its publication in Here he covered arrhythmias, on which he had been writing for years, with information on mechanisms and treatment, together with detailed discussion on illustrative cases.

Sinus node dysfunction: Among other publications on sinus node function, is an elegant article on the recognition and features of Wenckebach sino-atrial block. The clue to the Wenckebach mechanism is that the P—P interval shortens before the missing P wave, just as the R—R interval shortens before the dropped beat in the Wenckebach atrio-ventricular block. This is due to the fact that, while the P—R interval continues to lengthen, the increment diminishes.

An Introduction To Electrocardiography

The contribution of the P—R interval is therefore greatest for the first R—R interval of the sequence, and lessens thereafter. Bundle branch block and phasic aberrant ventricular conduction: Schamroth popularised the concept of phasic aberrant ventricular conduction, i. The concept of incomplete left bundle branch block LBBB had been demonstrated experimentally, but not clinically, until the article by Schamroth and Bradlow.

Because this occurred in the same patient and within a short time, it validated the existence and features of incomplete LBBB for the first time. In both of these articles, the mechanism of rate-related bundle branch block is clearly described and illustrated with diagrams.

Schamroth emphasised the importance of different refractory periods in the two bundle branches and the effects of changes in the R—R interval on His-Purkinje refractoriness.

The apparent paradox of aberration occurring when a premature supraventricular complex follows a longer R—R interval, whereas conduction is normal at the same prematurity if the preceding R—R is shorter, is accounted for by the bundle branch refractory period shortening in response to the shorter R—R.

Atrioventricular AV conduction and heart block: Schamroth wrote articles on many aspects of atrio-ventricular conduction, including concealed conduction, the supernormal phase and Wedensky facilitation.

Ventricular ectopy and parasystole: Schamroth was fascinated by ventricular ectopic rhythms. He was adept at detecting the far-from-obvious relationships between apparently unrelated ventricular complexes.


Ischaemic heart disease His books, articles and presentations covered all aspects of the subject, culminating in The Electrocardiology of Coronary Artery Disease.

One of his most memorable lectures was on the diagnosis of myocardial infarction in the presence of LBBB, which helped to debunk the myth that it could not be done. It was, however, Leo Schamroth who was responsible for resuscitating his reputation and highlighting his singular contribution to the science of electrocardiology. It was a theatrical masterpiece, which received wide acclaim and resulted in Craib being elected to the Society of Scholars of Johns Hopkins University, which had failed to protect him when he was falsely accused of plagiarism and shunned by his peers.

If clubbing is present, the normal gap between the bases of the nails is filled in. He communicated his enthusiasm and flair for unearthing the hidden meaning in tracings to all who came in contact with him.

His influence extended worldwide through his books, articles and lectures and he elevated the ECG from a clinical tool to an intellectual delight. He built upon the traditions of the Chicago School of Electrocardiography and was in the same league as Richard Langendorf and Alfred Pick. While he did not ignore the clinical significance and context of his many observations, his focus was on the detailed analysis of timing and associations of ECG events to reveal relationships that were hidden from the casual observer.

He was slow to embrace the rapidly developing field of invasive cardiac electrophysiology, although it confirmed many of the brilliant deductions made by him and others, based on the surface ECG alone. Most notably, he was reluctant to accept the concept of reentry as the basis of most sustained ventricular tachycardias, preferring the concept of focal ectopic tachycardias.

This was based on his calculations that ventricular conduction velocity and refractory periods largely precluded re-entry, although he conceded that bundle branch re-entry could occur. Schamroth concentrated much of his intellectual effort on the intricacies of ventricular ectopy, parasystole and the rule of bigeminy.

This work still stands as a monument to rigorous analysis, but its clinical significance is somewhat limited. His clear exposition of the phenomenon of phasic aberrant ventricular conduction is as valid today as it was then. It nevertheless still causes confusion and is sometimes enthusiastically over diagnosed by those less skilled in ECG interpretation, resulting in misdiagnosis of ventricular tachycardia as supraventricular. Conclusion Leo Schamroth was a giant in the field of deductive electrocardiography and achieved international renown.

We reproduce it all later on in this Blog post in Figure-5 and Figure-6 — and, we constantly reinforce clinical application of this system in all of the posts on our ECG Blog.

Admittedly — it may take longer initially to interpret tracings as you are getting used to the system.

NOTE: It does not matter if you decide to use our System presented in Figure-2 — or some other system you prefer — or even a composite of multiple systems. Consider the lead ECG in Figure The rhythm is sinus — as indicated by the upright P waves with fixed PR interval in lead II red arrow.


Does ST elevation in these same anterior leads — indicate that anteroseptal infarction may be acute? We admit that we deceptively labeled this ECG — in our best attempt to distract you to answer the questions we posed before performing systematic analysis.

We follow the 6-Parameter Checklist provided in Figure The mechanism is sinus — as determined by the presence of an upright P wave in lead II red arrow with a constant PR interval.

Intervals: The PR interval is normal not more than 1 large box in duration.

However — the QRS complex is wide clearly more than half a large box in duration. LBBB alters the direction of septal depolarization. Since the interventricular septum is the very first part of the ventricles to depolarize — this alteration in direction of septal activation affects Q wave formation when there is LBBB since Q waves are the very first part of the QRS complex.More Delivery Options.
