A fast rhythm with rates commonly 150-240/minute; QRS complex is most often narrow; rhythm is usually generated from a re-entry loop – often making use Read More

The atria and the ventricles are firing independently of each other (i.e. complete heart block and ventricular tachycardia). The presence of an entirely chaotic PR Read More

The atrioventricular (AV) valves lie between the atria and the ventricles of the right and left heart. The valves that connect the atria to the Read More

Atrioventricular blocks (AV blocks) result from a conduction disturbance at or just below the AV junction. The 3rd step of the 3 step process prompts Read More

These lead views are mathematically created from the limb electrodes to view the heart from three distinct positions towards the centre of the heart. Therefore, Read More

An electrical wave envelops the ventricles very quickly IF the Bundle Branches and the Purkinje Network are utilized. This is comparable to getting off the Read More

A cardiac cell’s (usually pacemaker cells such as the SA node, AV node or His-Purkinje network) ability to self-initiate an impulse; note that abundant catecholamines Read More

Involuntary nervous system consisting of the sympathetic and parasympathetic nervous systems. The autonomic nervous system has dramatic effects on the cardiovascular system. When regards to Read More

Conducts the impulse through the fibrous plate that separates the atria and the ventricles; consists of the AV node and the bundle of His; functions Read More
