Abstract
rrhythmias are common in the intensive care unit and represent a major source of morbidity and increased length of stay.
The sinoatrial node (SA node) is a natural pacemaker. It starts the electrical signal that travels across the upper 2 chambers or atria of the heart to the atrioventricular node (AV node).
The AV node transfers the electrical signal from the upper part of the heart to the lower 2 pumping chambers or ventricles. The bundle branches are specialized tissues that help send electrical impulses through the ventricles. This makes a normal heart beat, called normal sinus rhythm.
There are two major types of arrhythmias, tachyarrhythmia (the heart rate is too fast more than 100 beats per minute), and bradyarrthymia (the heart rate is too slow less than 60 beats per minute).
Tachyarrhythmia are classified according to the site of impulse generation in relation to the atrioventricular (AV) conduction system.Supraventricular tachycardias(SVT) originate above AV node and have normal QRS duration(=0.12 seconds).While ventricular tachycardias originate below AV node and have prolonged QRS duration. Each type of tachycardia can then be subdivided according to regularity of the rhythm.
Bradyarrythmias are classified to sinus bradycardia, sinus arrest and atrioventicular block which further subdivided into first, second and third degree heart block.
Artificial pacemakers are electronic devices that stimulate the heart with electrical impulses to maintain or restore a normal rhythm in people with slow heart rhythms. A variety of types of pacemakers have been developed to restore or sustain a regular heartbeat in different ways.
Temporary pacemakers are intended for short-term use during hospitalization.While Permanent pacemakers are those intended for long-term use. Pacemakers may be single, dual, or triple chambered.
Emergency indications of temporary pacemakers are acute myocardial infarction with asystole, symptomatic bradycardia, bilateral bundle branch block (BBB) or Mobitz type II second-degree AV block.
Pacemakers may cause undesirable complications during and after implantation. Complications associated with the implantation procedure are uncommon, but include bleeding, infection, or collapsed lung.
Pacemaker complications can be divided into acute (immediate) or chronic according to implantation time (or date). Lead or pocket complications according to the site of complication and implantation or system failure.
