A 15-year-old female patient presented at the clinic with heart failure (HF). A 12-lead electrocardiogram showed a heart rate of 170 bpm; negative P waves in leads DII, DIII, aVF; and long RP tachycardia (LRPT). Echocardiography demonstrated a shortening fraction (SF) of 20%. An electrophysiology study during tachycardia revealed an atrial-His time of 52 milliseconds and a His-atrial interval of 295 milliseconds. During ventricular entrainment, the postpacing interval-tachycardia cycle length was measured at 225 milliseconds. There was a pseudo V-A-A-V response. These findings confirmed the diagnosis of atypical atrioventricular nodal re-entrant tachycardia (aAVNRT). Successful slow pathway cryoablation was performed with an 8-mm-tip cryocatheter. After 2 weeks, the SF was measured as 34%. During a 2-year follow-up period, no recurrence was observed. In conclusion, fast-slow aAVNRT should be a part of the differential diagnosis of incessant LRPT leading to HF. Cryoablation can be used successfully in cases of aAVNRT.

Although cardiac arrest during airline flights is relatively uncommon, the unusual setting, limited resources, and the variability of the skills in medical volunteers present unique challenges. Survival in patients who suffer a witnessed arrest with a shockable rhythm who are treated promptly has improved since the advent of widely available automated external defibrillators (AEDs). In general, the chances of survival from an out-of-hospital cardiac arrest (OHCA) are greater when ventricular fibrillation (VF) is seen as the initial rhythm or if there is return of spontaneous circulation (ROSC). Not all in-flight cardiac arrests are witnessed because cabin crew or fellow passengers might simply assume that the victim is sleeping. Based upon a review of the literature on resuscitation after OHCA, we recommend that automatic external defibrillators be carried on all commercial airline flights, regardless of duration. Patients presenting with shockable rhythm (e.g., VF, unstable ventricular tachycardia) have the best prognosis for survival and usually require diversion of the aircraft for advanced cardiac life support (ACLS). Because diversion may require interruption of cardiopulmonary resuscitation (CPR) and may impact flight safety, the volunteer rescuer, cabin crew, flight crew, and medical consultation services should discuss the possible outcome and operational considerations before recommending a diversion for a patient with a nonshockable rhythm. The recommendations in this article were developed by members of the Air Transport Medicine and Aerospace Human Performance Committees and approved by the Council of the Aerospace Medical Association.Ruskin KJ, Ricaurte EM, Alves PM.

- Non - coronary predictors of elevated high-sensitive cardiac Troponin T (hs - cTnT) levels in an unselected emergency patient cohort. [Journal Article]
- CCClin Cardiol 2018 Jul 17
- CONCLUSIONS: In an unselected, non-ACS patient cohort age, chronic renal failure, inflammatory state, and reduced left ventricular systolic function were associated with hs-cTnT-levels above the upper reference limit. Rather, often supposed predictors as atrial fibrillation, hypertension, and tachycardia cannot sufficiently explain increased hs-cTnT in our study. Hence, further studies are needed to assess whether isolated hypertension, tachycardia, or atrial fibrillation sufficiently explain elevated hs-cTnT. This article is protected by copyright.

Three-dimensional mapping systems are used for the characterization and treatment of complex arrhythmias, such as atrial reentrant tachycardias, atrial fibrillation, or ventricular tachycardia. The Rhythmia™ mapping system (Boston Scientific, Natick, MA, USA) belongs to a novel generation of mapping systems that are able to rapidly create high-density and high-resolution three-dimensional maps in an automated manner. Mapping is performed with a magnetic- and impedance-based tracked bidirectional deflectable 64-pole basket catheter (IntellaMap Orion™, Boston Scientific). Based on previous studies, the system is effective and safe for the treatment of complex atrial and ventricular arrhythmias.

- HRHeart Rhythm 2018 Jul 12
- CONCLUSIONS: Subclinical myocardial injury and non-fatal cardiac arrhythmias can occur in the context of IRE treatment. While in follow up after three months no sustained cardiac injuries could be found, we do propose implementation of a cardiac safety algorithm when conducting IRE, consisting of cardiac biomarkers and ECG monitoring.
