Challenging Cardiac Electrophysiology [PDF]

open access: yesFrontiers in Physiology, 2010
At the launch of this new Journal in the field of cardiac electrophysiology, Frontiers in Cardiac Electrophysiology, one may wonder which challenges lie ahead in cardiac electrophysiology. Are the textbooks on cardiac electrophysiology complete? In the past century enormous progress has been made in the understanding of cardiac electrophysiology and

Atrial Fibrillation and Hyperthyroidism [PDF]

open access: yes, 2005
Atrial fibrillation occurs in 10 – 15% of patients with hyperthyroidism. Low serum thyrotropin concentration is an independent risk factor for atrial fibrillation. Thyroid hormone contributes to arrythmogenic activity by altering the electrophysiological

Stiffness‐Tunable Neurotentacles for Minimally Invasive Implantation and Long‐Term Neural Activity Recordings

open access: yesAdvanced Science, EarlyView.
A hydraulically actuated “Neurotentacle” probe offers tunable stiffness for precise implantation into the deep brain without rigid shuttles or dissolvable coatings. It stiffens during insertion to penetrate tissue and softens afterward to minimize damage and enable stable long‐term recordings.

Role of Implantable Cardioverter Defibrillators in the Treatment of Hypertrophic Cardiomyopathy [PDF]

open access: yes, 2005
Hypertrophic cardiomyopathy (HCM) is an important cardiovascular disease with sudden cardiac death as the most devastating presentation. Implantable cardioverter defibrillators (ICD) are the optimal therapy for prevention of sudden death from ventricular

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

P Wave Dispersion is Increased in Pulmonary Stenosis [PDF]

open access: yes, 2006
Aim: The right atrium pressure load is increased in pulmonary stenosis (PS) that is a congenital anomaly and this changes the electrophysiological characteristics of the atria.

Rapamycin Alleviates Heart Failure Caused by Mitochondrial Dysfunction and SERCA Hypoactivity in Syntaxin 12/13 Deficient Models

open access: yesAdvanced Science, EarlyView.
Rapamycin alleviates heart failure via TFEB and CaMKII pathways in Syntaxin 12/13 deficient models. Stx12 deficiency causes heart failure via impaired iron trafficking to mitochondria, reducing respiratory complexes and sarcoplasmic reticulum Ca2+‐ATPase (SERCA).

Advanced management of ventricular arrhythmias in chronic Chagas cardiomyopathy

open access: yesHeart Rhythm O2, 2021
Chagas cardiomyopathy is a parasitic infection caused by Trypanosoma cruzi. Structural and functional abnormalities are the result of direct myocardial damage by the parasite, immunological reactions, dysautonomia, and microvascular alterations.
