Respiratory sinus arrhythmia is actually a sign of a healthy heart. Wellens HJ, Br FW, Lie KI, The value of the electrocardiogram in the differential diagnosis of a tachycardia with a widened QRS complex, Am J Med, 1978;64(1):2733. Bundle Branch Block; Accessory Pathway; Ventricular rhythm Ventricular escape rhythm; AIVR - Accelerated Idioventricular Rhythm; One such example would be antidromic atrioventricular reciprocating tachycardia (AVRT), where the impulse travels anterogradely (from the atrium to the ventricle) over an accessory pathway (bypass tract), and then uses the normal His-Purkinje network and AV node for retrograde conduction back up to the atrium. The ECG recorded during sinus rhythm . , When this occurs, the change in R-R interval precedes and predicts the change in P-P interval; in other words, the R-R change drives the P-P change, confirming that this is VT with 1:1 VA conduction. Furthermore, there will often be evidence of VA dissociation, with the ventricular rate being faster than the atrial rate, pointing to the correct diagnosis of VT. Grant C. Fowler MD, in Pfenninger and Fowler's Procedures for Primary Care, 2020 Right Axis Deviation (Not Present on Prior Electrocardiograms) When right axis deviation is a new finding, it can be due to an exacerbation of lung disease, a pulmonary embolus, or simply a tachycardia. [Solved] #3 Interpret the ECG rhythm below: PRI: | Course Hero Its very common in young, healthy people. Healthcare providers often find sinus arrhythmia while doing a routine electrocardiogram (EKG). Wide Complex Tachycardia: Definition of Wide and Narrow. Conclusion: The nonsustained VT was actually a paced rhythm due to inappropriate and intermittent tracking of atrial fibrillation by the dual-chamber pacemaker. It should be noted that hemodynamic stability is not always helpful in deciding about the probable etiology of WCT. Past medical history was significant for type II diabetes, hypertension, hyperlipidemia, and chronic kidney disease (CKD). Wide QRS tachycardia may be due to ventricular tachycardia (VT), supraventricular tachycardia (SVT) with aberrant conduction, or atrioventricular reentrant tachycardia (AVRT) with an accessory pathway.
