Type I atrial flutter, counterclockwise rotation with 3:1 and 4:1 AV nodal block. Atrial flutter with a two to one block. Note the P waves hiding in the T waves in leads V1 and V2. Type I atrial flutter, also known as common atrial flutter or typical atrial flutter, has an atrial rate of 240 to 340 beats/minute.
Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, ...
Third-degree atrioventricular block (AV block) is a medical condition in which the electrical impulse generated in the sinoatrial node (SA node) in the atrium of the heart can not propagate to the ventricles. [1] Because the impulse is blocked, an accessory pacemaker in the lower chambers will typically activate the ventricles.
Second-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart.It is a conduction block between the atria and ventricles.The presence of second-degree AV block is diagnosed when one or more (but not all) of the atrial impulses fail to conduct to the ventricles due to impaired conduction.
Intraventricular conduction delay seen in precordial/chest leads with QRS duration 100 ms. An EKG of a 25-year-old male. Intraventricular conduction delays (IVCD) are conduction disorders seen in intraventricular propagation of supraventricular impulses resulting in changes in the QRS complex duration or morphology, or both.
Irregular "fluttering" suggests atrial fibrillation, atrial flutter, or tachycardia with variable block. [1] "pounding in the neck" or neck pulsations, often due to cannon A waves in the jugular vein. These occur when the right atriumcontracts against a closed tricuspid valve. [6] Palpitations often come with other symptoms.
Other diagnoses that may present with similar findings on electrocardiogram that should be included in the differential diagnosis include sinus tachycardia with frequent premature atrial contractions (this would have regular PP intervals), atrial flutter with variable AV node conduction (this would have regular PP intervals and flutter waves ...
Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
