Case evaluation A 12-lead baseline electrocardiogram at admission showed sinus rhythm without signs of ischemia. There were no abnormal findings on physical examination. Biochemical blood evaluation showed no abnormalities. An echocardiogram revealed a normal morphology and function of the heart. Holter monitoring revealed bouts of regular supraventricular tachycardia while eating, with a maxim...

452 markers were within the reference ranges. Base‐ line electrocardiogram (ECG) showed sinus rhythm with frequent ventricular extrasystoles and episodes of nonsustained ventricular tachy‐ cardia, without any conduction disorder. Flat T waves in the inferior leads (III, aVF) were pres‐ ent (FIGURE 1A). A 24 ‐hour ECG recording showed a sinus rhythm of 62 bpm with frequent episodes of polymorphi...

BACKGROUND AND OBJECTIVES Recent evidence indicates that the membrane voltage and Ca(2+) clocks jointly regulate sinoatrial node (SAN) automaticity. However, the mechanism of heart rhythm acceleration of the subsidiary pacemaker (SP) during β-adrenergic stimulation is still unknown. Here we tested the hypothesis that the heart rate acceleration of the SP by β-adrenergic stimulation involves syn...

Abstract Background Atrial fibrillation (AF) hospital admissions represent significant AF related treatment costs nationally. In the year 2019–2020 our reported 1,333 with a primary diagnosis of AF, 10% annual increase. A virtual ambulatory ward providing multidisciplinary care remote hospital-level monitoring could reshape future model management. Methods An was implemented at UK tertiary cent...

High-resolution spectra of the CN B2 summation operator +-X2 summation operator + (0,0) band at 390 nanometers yield isotopic ratios for comets C/1995 O1 (Hale-Bopp) and C/2000 WM1 (LINEAR) as follows: 165 +/- 40 and 115 +/- 20 for 12C/13C, 140 +/- 35 and 140 +/- 30 for 14N/15N. Our N isotopic measurements are lower than the terrestrial 14N/15N = 272 and the ratio for Hale-Bopp from measurement...

OBJECTIVES The objective of this study was to correlate electrocardiographic (ECG) PR interval changes during normal sinus rhythm with recent observations regarding the anatomy and physiology of the dual, slow and fast atrioventricular (AV) pathways. BACKGROUND The least common manifestation of dual AV conduction is an abrupt PR interval change in the setting of sinus rhythm. Whereas isolated...

A regular slow wave theta rhythm can be recorded in the medial entorhinal cortex (MEC) of freely moving rats during voluntary behaviors and paradoxical sleep. Electrode penetrations normal to the cortical layers proceeding from the deeper to the more superficial layers reveal a continuous theta rhythm in layers IV-III (deep MEC theta rhythm) with an amplitude maximum in layer III, a null betwee...

OBJECTIVE We aimed to determine upright heart rate and blood pressure (BP) changes to suggest diagnostic criteria for postural orthostatic tachycardia syndrome (POTS) and orthostatic hypertension (OHT) in Chinese children. METHODS In this cross-sectional study, 1449 children and adolescents aged 6-18 years were randomly recruited from two cities in China, Kaifeng in Henan province and Anguo i...

A 140 GHz transmitter (Tx) and receiver (Rx) chip set has been developed in 65 nm CMOS by using on– off keying non-coherent modulation to support high speed proximity data communication. To the author’s best knowledge, it enables the first integrated multi-Gbps data link in D-band by saving power hungry frequency synthesizer, high speed data convertors and complicated digital signal processor. ...
