9 Σεπ 2024 · Cardiac axis represents the sum of depolarisation vectors generated by individual cardiac myocytes. Clinically is is reflected by the ventricular axis, and interpretation relies on determining the relationship between the QRS axis and limb leads of the ECG (below diagram)
6 Μαρ 2011 · What is cardiac axis? Cardiac axis represents the overall direction of electrical activity as it spreads through the cardiac conduction system. In other words, it represents the net effect of all generated action potentials within the heart.
The cardiac axis refers to the general direction in which the heart depolarises. Each wave of depolarisation begins at the Sinoatrial node, then spreads to the Atrioventricular node, before travelling to the Bundle of HIS and the Purkinje fibres to complete an electrical cardiac cycle.
Cardiac conduction system - Wikipedia. The cardiac conduction system (CCS, also called the electrical conduction system of the heart) [1] transmits the signals generated by the sinoatrial node – the heart 's pacemaker, to cause the heart muscle to contract, and pump blood through the body's circulatory system.
19 Δεκ 2023 · Reading an ECG. ECG tracings are recorded on a specific type of paper, as shown in the example below. There are certain measurements to be aware of here: Small square = 0.04 secs. Large square (5 small squares) = 0.2 secs. 5 large squares = 1 second. 300 large squares = 1 minute. Fig 2 – The specifics of ECG recording paper.
Learn the principles of cardiac physiology, electrocardiography and ECG interpretation. The action potential and conduction system are also discussed.
