Design and Evaluation of a Diaphragm for Electrocardiography in Electronic Stethoscopes

We describe the development, experimental evaluation, and comparison of the ECG signals obtained using our proposed approach and a gold standard medical device, through metrics that allow the evaluation of morphological similarities. Results point to a high correlation between the two evaluated setups, thus supporting the idea of meaningfully collecting ECG data along medical auscultation points with the proposed form factor. Moreover, this work has led us to conclude that for the studied population, signals acquired on focuses F1, F2, and F3 are usually highly correlated with leads V1 and V2 of the standard ECG medical recording procedure.

Authors: Kakehashi S, Kamakura T, Aiba T, Kusano K Abstract We herein report a 47-year-old man with relapsing polychondritis who developed monomorphic ventricular tachycardia (VT). His electrocardiogram in sinus rhythm showed a coved-type pattern, and there was no evidence of structural cardiac disease; therefore, he was diagnosed with Brugada syndrome. An electrophysiological study revealed a prolonged His-ventricular interval at the baseline. Two forms of VT were induced, which were shown to be bundle branch reentrant VT. A diagnosis of Brugada syndrome should not be ruled out in patients with monomorphic VTs, es...

CONCLUSION: N1 showed moderate trypanocidal and promising immunomodulatory activities, and its use in combination with benznidazole and/or anti-arrhythmic drugs as well as the efficacy of its alternative formulations must be investigated in the near future.

The health tracking market is booming. What with smart bracelets, smart beds and smart chest straps, the tracking industry has penetrated the lives of old and young from the time they wake up in the morning to the time they hit the bed at night (and beyond). It’s no wonder that user penetration is projected to reach 25% of the adult population by 2022 in the US alone and that these devices are being adopted by over 30% of individuals across all age groups. Naturally, I count among those adopters. I call myself a data geek, using the data accumulated from myriads of health trackers to help me make more informed hea...

ConclusionThe final results of this study showed that there was no significant difference between the four study groups and arrhythmia status. Therefore, f-QRS was not introduced as an independent predictor of arrhythmia in patients with acute MI.

Authors: Takayanagi Y, Koike A, Kubota H, Wu L, Nishi I, Sato A, Aonuma K, Kawakami Y, Ieda M Abstract The pulse wave transit time (PWTT) is easily measured as the time from the R wave of an electrocardiogram to the arrival of the pulse wave measured by an oxygen saturation monitor at the earlobe. We investigated whether the change of PWTT during exercise testing reflects cardiopulmonary function. Eighty-nine cardiac patients who underwent cardiopulmonary exercise testing (CPX) were enrolled. We analyzed the change of PWTT during exercise and the relationship between the shortening of the PWTT and CPX parameters. P...

We examined low risk (LR) patients admitted to our chest pain unit (CPU) with negative cardiac injury markers, normal electrocardiogram, and clinical stability. We hypothesized that there is a sub-group of intermediate risk (IR) patients within the larger LR population. Methods: Criteria for IR were the aforementioned 3 indicators of LR and ≥1 of the following: (1) known coronary artery disease (CAD), (2) men ≥45 yo, women ≥55 yo, and (3) ≥3 cardiac risk factors. We compared patient characteristics, use of pre-discharge testing (PDT), and major adverse cardiac events (MACE). Results: IR patients numbered ...

Conclusions: AUD patients with excessive alcohol use had a higher risk of arrhythmia and sudden death compared to the control group. Consideration of ECG and referral to cardiologic examinations would contribute to the follow-up and health of patients with AUD. PMID: 32065846 [PubMed - in process]
