Electrocardiography

http://www.acadoodle.com Atrial depolarisation is transmitted to the ventricular myocardium by the AV node and intraventricular conducting system. The time between the onset of atrial depolarisation and the release of depolarisation into the ventricular myocardium from the terminal branches of the conducting system is represented by the PR interval on the ECG. Dysfunction of the AV node or diffuse damage to components of the ventricular conducting system can result in a delay or even failure of transmission of atrial depolarisation into the ventricular muscle mass. This situation is referred to as atrioventricular or AV block. Three degrees of AV block are recognised. First degree AV block is defined by transmission of all P waves to the ventricular myocardium but with prolongation of the PR interval beyond the upper limit of normal on the ECG. Second degree AV block is defined by failure of conduction of some P waves into the ventricles. In third degree or 'complete' AV block, no P waves are transmitted to the ventricular myocardium.

http://www.acadoodle.com The leads of the ECG machine detect the movement of the cardiac depolarisation and repolarisation waves as they spread through the atria and ventricles. Leads capable of detecting electrical signal are placed on the patient's body and the different lead positions record the flow of current through the heart from different perspectives. Iin this video we will explain how the individual ECG leads analyse and record cardiac current.  

http://www.acadoodle.com Atrial fibrillation is the commonest cardiac arrhythmia encountered in clinical practice. In this condition, chaotic electrical impulses, generated from multiple sites within the atria and pulmonary veins, result in irregular depolarisation of the ventricles with a resulting irregularly irregular heartbeat. Recognition of atrial fibrillation on the ECG is a crucial skill as the arrhythmia increases the risk of stroke and heart failure. These complications are preventable with appropriate treatment. Atrial flutter is a common arrhythmia which arises by a very specific mechanism. This arrhythmia is easily missed on the ECG.

http://www.acadoodle.com The combination of an unfortunately timed atrial ectopic and the existence of two strands of conducting tissue with opposite electrical properties in the junctional region of the heart can establish a rapidly discharging, self sustaining, re-entrant loop of depolarising current. This current will be discharged distally into the ventricles and also in a retrograde fashion into the atria. This is the mechanism underlying a common paroxysmal supraventricular tachycardia (SVT); AVNRT. We will explain the mechanism underlying AVNRT in this video. Understanding the underlying mechanism generating this tachycardia will help you identify this common arrhythmia on the ECG.

http://www.acadoodle.com Isolated dysfunction or damage of either of the main branches of the bundle of His is commonly observed in clinical practice. The pattern of ECG changes associated with right and left bundle branch block are predictable and you must be able to recognise them on the ECG. Complete right bundle branch block (RBBB) and complete left bundle branch block (LBBB) produce prolongation of the qrs complex and predictable morphological changes on the ECG.

http://www.acadoodle.com In this video we review the nomenclature of the ECG readout. You will learn that the deflection produced by atrial depolarisation is termed a P wave while ventricular depolarisation produces the qrs complex. You will also learn the correct nomenclature of individual deflections within the qrs complex and some important terms used in ECG analysis.

http://www.acadoodle.com The different leads of the ECG examine cardiac electrical activity from different perspectives. In this video we teach you the perspectives of the 12 ECG leads on cardiac depolarosiation and repolarisation. We consider the 12 leads in two groups of six, with the six chest leads (V1-V6, also referred to as the precordial leads) examining the flow of cardiac depolarisation and repolarisation in the horizontal plan and a second group of six leads (the standard leads and augmented leads) which examine these events in the vertical plane. For the experienced practitioner, looking at different areas on the ECG readout is like looking at different anatomical regions of the heart. Also, understanding the lead perspectives is crucial in the interpretation of cardiac arrhythmias.
