Paroxysmal Supraventricular Tachycardia: Differential Diagnoses & Workup - eMedicine Cardiology
emedicine.medscape.com — “Diagnosis: Supraventricular tachycardia (SVT), a common clinical condition, is any tachyarrhythmia that requires atrial and/or atrioventricular (AV) nodal tissue for its initiation and maintenance. It is usually a narrow-complex tachycardia that has a regular, rapid rhythm; exceptions ...” View full resource at emedicine.medscape.com

Second-Degree Atrioventricular Block: eMedicine Cardiology
emedicine.medscape.com — “Overview: Second-degree atrioventricular (AV) block is characterized by disturbance, delay, or interruption of impulse conduction through the AV node. This excludes block due to premature atrial beats. The AV block can be permanent or transient, depending on ...” View full resource at emedicine.medscape.com
