If a patient has a regular heart rhythm their heart rate can be calculated using the following method:. As a result, you need to apply a different method:.

Mark out several consecutive R-R intervals on a piece of paper, then move them along the rhythm strip to check if the subsequent intervals are similar.

If you are suspicious that there is some atrioventricular block AV block , map out the atrial rate and the ventricular rhythm separately i. As you move along the rhythm strip, you can then see if the PR interval changes , if QRS complexes are missing or if there is complete dissociation between the two.

Cardiac axis describes the overall direction of electrical spread within the heart. Read our cardiac axis guide to learn more. If P waves are absent and there is an irregular rhythm it may suggest a diagnosis of atrial fibrillation. A prolonged PR interval suggests the presence of atrioventricular delay AV block. To help remember the various types of AV block, it is useful to know the anatomical location of the block within the conducting system.

If the PR interval is shortened , this can mean one of two things:. When assessing a QRS complex, you need to pay attention to the following characteristics :. To assess morphology , you need to assess the individual waves of the QRS complex. The early activation then spreads slowly across the myocardium causing the slurred upstroke of the QRS complex. This requires evidence of tachyarrhythmias AND a delta wave.

Isolated Q waves can be normal. A single Q wave is not a cause for concern — look for Q waves in an entire territory e. Poor progression i. High take-off or benign early repolarisation to give its full title is a normal variant that causes a lot of angst and confusion as it LOOKS like ST elevation. T waves represent repolarisation of the ventricles. Biphasic T waves have two peaks and can be indicative of ischaemia and hypokalaemia.

Flattened T waves are a non-specific sign, that may represent ischaemia or electrolyte imbalance. These become larger the slower the bradycardia — classically U waves are seen in various electrolyte imbalances , hypothermia and secondary to antiarrhythmic therapy such as digoxin, procainamide or amiodarone.

This allows us to get in touch for more details if required. Confirm details Before beginning ECG interpretation, you should check the following details: Confirm the name and date of birth of the patient matches the details on the ECG. Check the date and time that the ECG was performed. Divide by this number to calculate heart rate.

Hint If you are suspicious that there is some atrioventricular block AV block , map out the atrial rate and the ventricular rhythm separately i. Hint If P waves are absent and there is an irregular rhythm it may suggest a diagnosis of atrial fibrillation. Tips for remembering types of heart block To help remember the various types of AV block, it is useful to know the anatomical location of the block within the conducting system.

Third-degree AV block: Occurs at or after the AV node resulting in a complete blockade of distal conduction. Join the community.

PBJ is an online free-to-submit and open-access journal devoted to the publication of top quality original research conducted in the biomedical fields, especially within the clinical and basic medical settings. The project aims to provide a valuable collection of generalist biomedical literature freely accessible to the international community, in order to become a reference in the current scientific landscape. In addition, to ensure the quality and scientific relevance of PBJ, the journal counts with a diversified and international editorial board, and only accepts original research and review articles that undergo a strict revision process in a double-blind refereeing system, a procedure that safeguards the fairness of the article selection process. As a generalist journal, PBJ accepts both original works and reviews in all biomedical areas, be they basic or clinical research.

The recording of 12 lead electrocardiograms ECG is one of the most useful and commonly performed medical procedures. ECGs are used in diagnosis, risk-stratification management decision-making, and assessment in response to therapy. The correct interpretation of 12 lead ECG recordings is complex and clinically challenging with misinterpretation having the potential to result in poor outcomes or even patient fatality. Despite its widespread use, several studies have highlighted deficiencies in ECG interpretation skills among health professionals. The pedagogy of ECG interpretation lacks universal establishment; time allocation, faculty training and teaching format vary considerably within the literature.

Metrics details. Electrocardiogram ECG interpretation is of great importance for patient management. However, medical students frequently lack proficiency in ECG interpretation and rate their ECG training as inadequate. Our aim was to examine the effect of a standalone web-based ECG tutorial and to assess the retention of skills using multiple follow-up intervals.

 Этот полицейский… - Клушар рассердился.  - Он уронил меня с мотоцикла, бросил на улице, залитого кровью, как зарезанную свинью. Я еле добрел. - Он не предложил вам больницы поприличнее.

В случае перегрева он выключится без чьей-либо помощи. - Вы сумасшедший, - с презрением в голосе ответил Хейл.  - Мне наплевать, даже если ваш ТРАНСТЕКСТ взлетит на воздух.

 - Теперь, мистер Клушар, позвольте спросить, почему такой человек, как вы, оказался в таком месте.

Существовал только один разумный путь - выключить. Чатрукьян знал и то, что выключить ТРАНСТЕКСТ можно двумя способами. Первый - с личного терминала коммандера, запертого в его кабинете, и он, конечно, исключался. Второй - с помощью ручного выключателя, расположенного в одном из ярусов под помещением шифровалки. Чатрукьян тяжело сглотнул.

Хотя в последнее мгновение Беккер увернулся, Халохот сумел все же его зацепить. Он понимал, что пуля лишь слегка оцарапала жертву, не причинив существенного ущерба, тем не менее она сделала свое. Контакт был установлен. Жертва ощутила прикосновение смерти, и началась совершенно иная игра. Беккер мчался, не видя ничего вокруг, постоянно сворачивал, избегая прямых участков. Шаги неумолимо приближались.

И взмолилась о том, чтобы они сумели вовремя найти Северную Дакоту. - Поторопись, - крикнул ей вдогонку Стратмор, - и ты еще успеешь к ночи попасть в Смоки-Маунтинс. От неожиданности Сьюзан застыла на месте. Она была уверена, что никогда не говорила с шефом о поездке. Она повернулась. Неужели АНБ прослушивает мои телефонные разговоры. Стратмор виновато улыбнулся.

    The ECG is the oldest cardiologic test, but even years after its inception, it continues as the most commonly used cardiologic test.
