BIOC34H3 Study Guide - Second-Degree Atrioventricular Block, Heart Block, Diastole
Document Summary
Bipolar ecg limb leads record the voltage b/n electrodes placed on the wrists and the arms: this forms an equilateral triangle around the heart, referred to as einhoven"s. any depolarisation in the direction of the left leg (always +) will give a positive inflection on the trace. any depolarisation in direction of right arm (always -) will give negative inflection on the trace www. notesolution. com. Ecg waves: p wave: atrial depolarisation (small cause of less muscle mass than ventricles, qrs complex: depolarisation of ventricles and repolarisation of atrium (silent atrium repolarisation). Blip sound you hear: t wave: ventricular repolarisation. Important ecg wave and conduction co-ordination pathway: slide 8 15. Augmented unipolar limb leads: use exactly the same type of leads as bipolar limb leads, with exception of all destinations being positive. Just a series of six leads v1 v6 placed all over upper body. Dysfunctional av node: first degree heart block: slide 27.
