noninvasive Cardiac Monitoring for detecting paroxysmal atrial fibrillation or flutter after acute ischemic stroke a systematic review
Stroke, 2007Co-Authors: Joy Liao, Zahira Khalid, Ciaran Scallan, Carlos A Morillo, Martin OdonnellAbstract:Background and Purpose— Identifying paroxysmal atrial fibrillation/flutter is an essential part of the etiological workup of patients with ischemic stroke. However, there is controversy in the literature regarding the use of noninvasive Cardiac rhythm Monitoring with previous reviews reporting a low detection rate with routine Monitoring. We performed a systematic review to determine the frequency of occult atrial fibrillation/flutter detected by noninvasive methods of continuous Cardiac Monitoring after acute ischemic stroke or transient ischemic attack. Methods— Studies were identified from comprehensive searches of PubMed, EMBASE, Science Citation Index, and bibliographies of relevant articles. Only English language articles were included. Randomized controlled trials and prospective cohort studies of consecutive patients with acute ischemic stroke that fulfilled predefined criteria were eligible. Two authors conducted searches and abstracted data from eligible studies independently. Results— Sixty stu...

a 1 06 mu w smart ecg processor in 65 nm cmos for real time biometric authentication and personal Cardiac Monitoring
IEEE Journal of Solid-state Circuits, 2019Co-Authors: Shihui Yin, Deepak Kadetotad, Minkyu Kim, Yang Liu, Chisung Bae, Sang Joon Kim, Yu Cao, Jaesun SeoAbstract:Many wearable devices employ the sensors for physiological signals (e.g., electrocardiogram or ECG) to continuously monitor personal health (e.g., Cardiac Monitoring). Considering private medical data storage, secure access to such wearable devices becomes a crucial necessity. Exploiting the ECG sensors present on wearable devices, we investigate the possibility of using ECG as the individually unique source for device authentication. In particular, we propose to use ECG features toward both Cardiac Monitoring and neural-network-based biometric authentication. For such complex functionalities to be seamlessly integrated in wearable devices, an accurate algorithm must be implemented with ultralow power and a small form factor. In this paper, a smart ECG processor is presented for ECG-based authentication as well as Cardiac Monitoring. Data-driven Lasso regression and low-precision techniques are developed to compress neural networks for feature extraction by 24.4 $\times $ . The 65-nm testchip consumes 1.06 $\mu \text{W}$ at 0.55 V for real-time ECG authentication. For authentication, equal error rates of 1.70%/2.18%/2.48% (best/average/worst) are achieved on the in-house 645-subject database. For Cardiac Monitoring, 93.13% arrhythmia detection sensitivity and 89.78% specificity are achieved for 42 subjects in the MIT-BIH arrhythmia database.

a 1 06 μw smart ecg processor in 65 nm cmos for real time biometrie authentication and personal Cardiac Monitoring
Symposium on VLSI Circuits, 2017Co-Authors: Deepak KadetotadAbstract:A smart wearable electrocardiographic (ECG) processor is presented for secure ECG-based biometric authentication and Cardiac Monitoring, including arrhythmia and anomaly detection. Data-driven Lasso regression and low-precision techniques are developed to compress the neural networks by 24.4X. The prototype chip fabricated in 65 nm LP CMOS consumes 1.06 μW at 0.55 V for real-time ECG authentication. Equal error rates of 0.74% and 1.7% are achieved on ECG-ID database and in-house 645-subject database, respectively.

arrhythmic burden as determined by ambulatory continuous Cardiac Monitoring in patients with new onset persistent left bundle branch block following transcatheter aortic valve replacement the mare study
Jacc-cardiovascular Interventions, 2018Co-Authors: Josep Rodescabau, Marc W. Deyell, Marina Urena, Luis Nombelafranco, Ignacio J Amatsantos, Neal S Kleiman, Antonio J Munozgarcia, Felipe Atienza, Vicenc Serra, Gabriela VeigafernandezAbstract:Abstract Objectives The authors sought to determine: 1) the global arrhythmic burden; 2) the rate of arrhythmias leading to a treatment change; and 3) the incidence of high-degree atrioventricular block (HAVB) at 12-month follow-up in patients with new-onset persistent left bundle branch block (LBBB) following transcatheter aortic valve replacement (TAVR). Background Controversial data exist on the occurrence of significant arrhythmias in patients with LBBB post-TAVR. Methods This was a multicenter prospective study including 103 consecutive patients with new-onset persistent LBBB post-TAVR with the balloon-expandable SAPIEN XT/3 valve (n = 53), or the self-expanding CoreValve/Evolut R system (n = 50). An implantable Cardiac monitor (Reveal XT, Reveal Linq) was implanted at 4 (3 to 6) days post-TAVR, and patients had continuous electrocardiogram Monitoring for 12 months. All arrhythmic events were adjudicated in a central electrocardiography core lab. Primary endpoints were the incidence of arrhythmias leading to a treatment change, and the incidence of HAVB at 12-month follow-up. Results A total of 1,553 new arrhythmic events were detected in 44 patients (1,443 episodes of tachyarrhythmia in 26 patients [atrial fibrillation/flutter/atrial tachycardia: 1,427, ventricular tachycardia 16]; 110 episodes of bradyarrhythmia in 21 patients [HAVB 54, severe bradycardia 56]). All arrhythmic events were silent in 34 patients (77%), the arrhythmic event led to a treatment change in 19 patients (18%), and 11 patients (11%) required pacemaker or implantable cardioverter-defibrillator implantation (due to HAVB, severe bradycardia, or ventricular tachycardia episodes in 9, 1, and 1 patient, respectively). A total of 12 patients died at 1-year follow-up, 1 from sudden death. Conclusions A high incidence of arrhythmic events was observed at 1-year follow-up in close to one-half of the patients with LBBB post-TAVR. Significant bradyarrhythmias occurred in one-fifth of the patients, and PPM was required in nearly one-half of them. These data support the use of a Cardiac Monitoring device for close follow-up and expediting the initiation of treatment in this challenging group of patients.

Managing tricyclic antidepressant overdose.
American Family Physician, 1992Co-Authors: Haddad LmAbstract:Tricyclic antidepressant overdose is the most common cause of death from prescription drugs. Clinical presentation of overdose from the tricyclic agents includes Cardiac arrhythmias, hypotension, seizures, coma and anticholinergic signs such as hyperthermia, flushing and intestinal ileus. The highly toxic/lethal level (greater than 1,000 ng per mL) is manifested on electrocardiograms as prolongation of the QRS interval to 100 milliseconds or more. Treatment includes establishment of an airway, proper oxygenation and ventilation, fluid replacement at maintenance levels, Cardiac Monitoring, gastric lavage and charcoal administration, alkalinization to a blood pH of 7.5 with intravenous sodium bicarbonate, supportive therapy and continued Cardiac Monitoring after clinical recovery.
