984 miliseconds (time interval between two sinus beats) 1375 miliseconds (time interval between two nodal beats): 3 The ECG When the Patient has a Tachycardia Mechanism of tachycardias Enhanced automaticity and triggered activity Abnormalities of cardiac rhythm due to re-entry Differentiation between re-entry and enhanced automaticity Tachycardias with symptoms Sinus rhythm causing symptoms Extrasystoles causing symptoms Narrow complex tachycardias causing symptoms Broad complex tachycardias … This rhythm strip illustrates a junctional escape rhythm. The sinus rhythm has slowed or stopped, and the junctional tissue has taken over as the pacemaker of the heart. The "junction" is loosely defined as the area between the AV node and the Bundle of His. The intrinsic rate of the pacemaking tissue in this area is 40 - 60 beats per minute. Focus topic: Atrial/AV Nodal and Junctional Dysrhythmias Patients who present with PSVT are usually symptomatic. They may complain of dizziness, shortness of breath, chest discomfort, palpitations, lightheadedness, near syncope, syncopal episodes, anxiety, heart failure, decreased mentation, nausea, vomiting, and general weakness. The health care provide may be able to see the heart beats in 2020-08-01 AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm.It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His.AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia.

The rate of spontaneous depolarisation of pacemaker cells decreases down the conducting system: SA node (60-100 bpm) Atria (< 60 bpm) AV node (40-60 bpm) atrioventricular junctional rhythm a junctional rhythm originating in the bundle of His, with a heart rate of 40 to 60 beats per minute; called also nodal rhythm. automatic rhythm spontaneous rhythms initiated by the sinoatrial node, or by subsidiary atrial or ventricular pacemakers; in practice this refers to a normal sinus rhythm at a rate of 60 to 100 beats per minute. Accelerated Junctional Rhythm Overview Accelerated junctional rhythm (AJR) occurs when the rate of an AV junctional pacemaker exceeds that of the sinus node.

Heart Dynamic – When lost, look to the heart
If electrical activity from SA node (sinus rhythm), then ECG reflects upright P wave + narrow QRS complex. But – If electrical activity from AV node (nodal rhythm) = P wave absent + narrow QRS complex Rhythm Abnormalities. Rhythms can originate in 3 places in the heart – the SA node, the region around the AV node (known as nodal, or junctional rhythm), or the ventricular muscle. Sinus Rhythm. This means that the rhythm of the heart is being controlled by the SA node – i.e.
