Wenckebach phenomenon (W.P.) at sites other than A-V junctional area
Abstract:
W.P. occurring at sites other than A-V junctional area are reported. Some of the cases are rather rare. His bundle electrography may be the best method in discovering the site of block, but the using of conventional ECG is also able to detect a correct diagnosis. Clinical significance are discussed, some are innocent, some are related to serious heart disease. Thorough examination is necessary before arriving at any conclusion.

Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
