Supraventricular Tachycardia (SVT) • LITFL • ECG Library Diagnosis
2024年10月8日 · The PR interval is ~ 120 ms, so this could be either a low atrial tachycardia or possibly an AVNRT with a long RP interval (i.e. either Fast-Slow or Slow-Slow varieties)
Long and short RP tachycardias - Johnson's Techworld
2008年10月18日 · Long and short RP tachycardias are two groups of supraventricular tachycardias depending on the interval between the R wave and the P wave of the next cycle. Short RP tachycardia. Typical (slow-fast tachycardia) AV nodal reentrant tachycardia [AVNRT] is the most common type of short RP supraventricular tachycardia.
Diagnosis and Ablation of Long RP Supraventricular Tachycardias
Long RP tachycardias are a unique collection of arrhythmias that include atypical (fast-slow) atrio-ventricular nodal reentrant tachycardia (AVNRT) with and without a concealed, bystander nodo-fascicular/ventricular accessory pathway (AP), orthodromic …
Long RP interval tachycardia. What is the mechanism? - PMC
Long RP tachycardia involving concealed nodofascicular accessory pathways (NFRT) are rare. PJRT and NFRT share electrophysiological features and differential criteria except the ΔAH. ΔAH>40 ms or the paradoxical finding of AH (SVT) <AH (NSR) support the diagnosis of NFRT.
Spotting the difference: short versus long RP tachycardia explained
This is called a long RP tachycardia because the P wave is farther from the prior QRS complex and closer to the subsequent QRS complex. Long RP tachycardia can also be seen in an unusual form of AVRT called permanent junctional reciprocating tachycardia (PJRT).
Long-RP supraventricular tachycardia: What is the mechanism?
2006年12月28日 · The tachycardia is characterized by an RP interval that is longer than the PR interval (long-RP tachycardia) and negative P waves in the inferior leads. The differential diagnosis of the tachycardia includes atypical (fast–slow) atrioventricular nodal reentrant tachycardia (AVNRT), orthodromic reciprocating tachycardia using a slowly ...
This is called a long RP tachycardia because the P wave is farther from the prior QRS complex and closer to the subsequent QRS complex. Long RP tachycardia can also be seen in an unusual form of AVRT called permanent junctional reciprocating tachycardia (PJRT).
Long RP Tachycardia: Diagnostic and Therapeutic Challenges: …
2016年2月29日 · A long RP narrow QRS complex tachycardia (Tach-1) was readily induced by atrial extrastimuli during isoproterenol infusion . The tachycardia cycle length (TCL), AH interval, HV interval, and VA interval were 318, 75, 46, and 239 ms, respectively.
Regular, narrow QRS, long RP tachycardia – what is the …
2016年9月16日 · The differential diagnosis of a regular, narrow QRS, long-RP tachycardia includes atypical atrioventricular nodal reentry tachycardia (AVNRT), atrial tachycardia and atrioventricular reentry tachycardia (AVRT) via a slowly conducting accessory pathway usually presenting decremental conduction properties.
What is the mechanism of the tachycardia? The tachycardia is characterized by an RP interval that is longer than the PR interval (long-RP tachycardia) and neg-ative P waves in the inferior leads.
