Artificial Intelligence Uses ECGs to Predict A-Fib Risk

TUESDAY, Nov. 12, 2019 -- In two studies, artificial intelligence was used with electrocardiogram (ECG) results to identify patients who are at increased risk for a potentially dangerous irregular heartbeat, and those more likely to die within a...

Authors: Okutucu S, Fatihoglu SG, Sabanoglu C, Bursa N, Sayin BY, Aksoy H, Oto A Abstract BACKGROUND: Angiotensin receptor neprilysin inhibitors (ARNI; sacubitril/valsartan combination) decrease morbidity and mortality in heart failure with reduced ejection fraction (HFrEF). Increased P‑wave duration and P‑wave dispersion (Pd) reflect prolongation of atrial conduction and correlate with atrial fibrillation. Here, we aimed to assess the effects of switching from valsartan to ARNI treatment on the basis of P‑wave indices. METHODS: A total of 28 patients with HFrEF (mean age, 64.8 ±&thinsp...

CONCLUSION: NT-proBNP may be a sensitive but nonspecific biomarker for assessing CA. However, CMR is the only imaging modality that can assess the pathophysiologic background of cardiac hypertrophy and the severity of CA, irrespective of NT-proBNP level.

Authors: Taguchi M, Sasa T, Izuhara M, Shioji K, Iwamuro A, Uegaito T, Matsuda M Abstract We herein report a case of congenital long QT syndrome (LQTS) in which the QT interval was prolonged by Takotsubo syndrome (TTS), inducing ventricular fibrillation (VF). The patient was a 55-year-old woman who had been diagnosed with LQTS. Cardiopulmonary arrest occurred while coughing during sleep. VF was observed, and her heartbeat returned after two defibrillations. An electrocardiogram showed marked QT prolongation and large negative T waves. Echocardiography demonstrated hyperkinesis at the base of the left ventricle and ...

CONCLUSION: We conclude that chronic topical timolol administration may aggravate a cardiac conduction defect leading to an AV block that is only temporarily resolved by timolol cessation. Patients taking timolol should be routinely monitored for cardiovascular aberrations and if any detected, immediately discontinue timolol therapy. Individuals experiencing timolol induced cardiovascular side effects should receive long term follow-up even if symptoms resolve, as they may be indicative of an underlying conduction defect.

AbstractNon-left bundle branch block (non-LBBB) remains an uncertain indication for cardiac resynchronization therapy (CRT). Non-LBBB includes right bundle branch block (RBBB) and non-specific LV conduction delay (NSCD), two different electrocardiogram (ECG) patterns which are not generally considered to be associated with LV conduction delay as judged by the invasive assessment of the Q-LV interval. We evaluated whether a novel ECG interval (QR-max index) correlated with the degree of LV conduction delay regardless of the type of non-LBBB ECG pattern, and could, therefore, predict CRT response. In 173 non-LBBB patients on...

AbstractSurgical pleth index (SPI) has been widely investigated in assessing the nociceptive level. The aim of this study was to investigate the relationship between SPI level and patient responses to trachea intubation and skin incision. A total of 40 patients undergoing open abdominal general surgery were recruited for analyses. The patients were monitored with electrocardiogram, non-invasive blood pressure, SpO2, invasive blood pressure and SPI before anesthesia induction. Anesthesia was induced with midazolam, propofol, sufentanil and rocuronium and maintained with sufentanil and sevoflurane. Blood pressure, heart rate...

Conclusion of this paper: Fever is a great risk factor for arrhythmia events in Brugada Syndrome patients. Patients with known fever-triggered Brugada syndrome should be surveilled closely during fever and be started on antipyretic therapy as soon as possible.  There are limited data regarding the impact of EP study in BrS patients triggered by fever.  An EP study might be helpful in symptomatic patients (Sroubek et al., 2016) in the presence of spontaneous BrS ECG or drug-induced ECG.The prognostic significance of fever-induced Brugada syndrome.  Heart Rhythm 2016.Eighty-eight asymptomatic patient...

AbstractBackgroundPacemaker battery depletion triggers alert for replacement notification and results in automatic reprogramming, which has been shown to be associated with relevant cardiorespiratory symptoms and adverse clinical events.ObjectiveDetermine if electrocardiogram (ECG) pacing features may be predictive of pacemaker battery depletion and clinical risk.MethodsThis is an ECG substudy of a cohort analysis of 298 subjects referred for pacemaker generator replacement from 2006 to 2017. Electronic medical record review was performed; clinical, ECG, and pacemaker characteristics were abstracted. We applied two ECG pre...
