	Reference Encyclopedia - Bundle branch block
		When bundles are injured, as in a myocardial infarction, or because of underlying heart disease, a bundle or a branch of a bundle may cease normal function.
		Right bundle branch blocks typically cause some prolongation of the last part of the QRS wave complex, and may cause the heart's electrical axis to be more rightward.
		However, when bundle blocks are complex and diffuse in the bundle systems, or associated with additional and significant ventricular muscle damage, they may be a sign of serious underlying heart disease.

		Third degree heart block, also known as ''complete heart block'', is a disease of the electrical system of the heart, in which the impulse generated in the top half of the heart (typically the SA node in the right atrium) does not propagate to the left or right ventricles.
		In a subset of individuals with the triad of first degree heart block, right bundle branch block, and either left anterior or left posterior fascicular block (known as trifascicular heart block) may be at an increased risk of progression to complete heart block.
		Mobitz I heart block is characterized by progressive prolongation of the PR interval on the electrocardiogram (EKG) on consecutive beats followed by a blocked beat (dropped QRS complex).

	Heart block - The Doctors Lounge(TM)
		AV (atrio-ventricular) block occurs when an atrial impulse is conducted with delay or fails to conduct to the ventricle at a time when the AV node should not be refractory.
		Trifascicular heart block is the triad of first degree heart block, right bundle branch block, and either left anterior or left posterior heart block seen on an electrocardiogram (EKG).
		In complete heart block, the atrial rate typically exceeds the ventricular rate, with no fixed relation between atrial and ventricular activity (AV dissociation), and the ventricular rate usually is regular, owing to the regularity of the escape rhythm focus.

	Heart block - second degree heart block
		Blocks that complete heart heart condition left bundle branch block block treatment occur within the sinoatrial node heart + tulipquilt block (SA node) are described as SA nodal blocks.
		The difference between SA node block and SA node suppression is that in SA node block an electrical definition heart block impulse is generated by the SA node that doesn't conduct to the ventricles.
		Of electrical heart block these types of infrahisian block, Mobitz II heart block is considered most important because of the possible progression to complete heart block.

	Heart Block
		Heart Block is a type of bradycardia (too-slow heartbeat) that also is called atrioventricular, or AV block.
		In this condition, the electrical signals that stimulate heart muscle contractions are partially or totally blocked between the upper chambers (atria) and the lower chambers (ventricles).
		Trifascicular block occurs when an individual is diagnosed with a form of bifascicular block as well as a first-degree heart block.

	Bradycardia
		In 2:1 block, a narrow QRS complex and associated periods of Wenckebach block, or simultaneous sinus slowing ("vagotonic block"), suggest that atrioventricular nodal block is present, whereas a wide QRS complex suggests the presence of infranodal block.
		Its ability to assess the risk of future atrioventricular block is limited, however, except at extreme HV intervals (the conduction intervals between the His bundle and the ventricular myocardium).
		Heart rates between 30 and 35 beats per minute, sinus pauses of 2.5 seconds or less, sinoatrial block, junctional rhythms, and first-degree and second-degree atrioventricular nodal block are common enough during sleep to be considered normal variants.

		From there, the electrical impulses travel through the upper chambers of the heart and to the atrioventricular (AV) node, where they are transmitted to the lower chambers of the heart ventricles via the "bundle branches." Thus, the electrical impulses travel from the sinoatrial node to the ventricles, to trigger and regulate the heartbeat.
		For example, sinus arrhythmia is a type of heart rhythm that originates in the normal area of the heart (sinus node) but is characterized by a variability in the heart rate.
		This is a procedure in which catheters are introduced into the heart from blood vessels in the legs and/or neck and radiofrequency energy is used to very carefully destroy (ablate) the abnormal areas of the heart that are creating the arrhythmias.

	Re: bradycardia & pacemakers
		Sinoatrial exit block is similar to sinus arrest on the ECG tracing but may be distinguished from sinus arrest by the fact that the duration of the pause is a multiple of the sinus P-P interval.
		An intrinsic heart rate close to the predicted rate in a patient with clinical SND is suggestive of an autonomic dysfunction as a cause of the bradyarrhythmia.
		It may be falsely shortened by SAN entrance block during atrial pacing (due to failure of the paced impulse to "reset" the sinus node) or falsely prolonged by a SAN exit block (the sinus node is normal but the impulse cannot leave the node).

	Left block
		Blocks in the anterior division of the left bundle and in the right bundle are shown diagrammatically.
		Left anterior hemiblock and right bundle branch block may be caused by obstruction of the anterior descending branch of the left coronary artery since this supplies both the right bundle and anterior division of the left.
		There is also probably a higher incidence of complete heart block in individuals with this condition than in those with anterior hemiblock and right bundle branch block, although the same indications for pacemaker implantation obtain.
