Initial dynamics of the EKG during an electrical defibrillation of the heart [PDF]

In tests on 11 mature dogs, immobilized by means of an automatic blocking and synchronization system, artefact free EKG were obtained, beginning 0.04-0.06 sec after passage of a defibrillating current. Different versions of the start of fibrillation were

Emerging Triboelectric Nanogenerators for In‐Body Implantation

Small Methods, EarlyView.
This review explores functional implantable triboelectric nanogenerators in biomedical applications, discussing their mechanisms, electricity generation, and design approaches. To solve postimplantation challenges, four types of triboelectric nanogenerators (TENGs) are introduced: stretchable, bioadhesive, on‐demand biodegradable, and multiresponsive ...

Comparison of Benefits from Cardiac Resynchronization Therapy between Patients with Ischemic Cardiomyopathy and Patients with Idiopathic Dilated Cardiomyopathy [PDF]

Journal of Tehran University Heart Center, 2009
Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with moderate to severe heart failure. However, 20-30% of patients remain non-responders to CRT.

Synchronization interfaces and overlapping communities in complex networks

, 2008
We show that a complex network of phase oscillators may display interfaces between domains (clusters) of synchronized oscillations. The emergence and dynamics of these interfaces are studied in the general framework of interacting phase oscillators ...

The neurochemical basis of photic entrainment of the circadian pacemaker [PDF]

Circadian rhythmicity in mammals is controlled by the action of a light-entrainable hypothalamus, in association with two cell clusters known as the supra chiasmatic nuclei (SCN).

Integrative Approach - New Level Knowledge of Functions: Opportunities and Prospects [PDF]

, 2012
In this article, the example of the mechanisms of heart rhythmogenesis in the intact organism is used to demonstrate the new capabilities provided by an integrative approach. It is shown that the rhythm is formed in the brain, transmitted to the heart in

Differences and Commonalities of Electrical Stimulation Paradigms After Central Paralysis and Amputation

Artificial Organs, EarlyView.
Invasive and non‐invasive functional electrical stimulation (FES) is a well‐established method to partially restore function after paralysis and deliver sensory feedback after amputation. This work summarizes the current state‐of‐the‐art of FES for restoring function, supporting rehabilitation therapy, and assistive devices.

Problems of artificial pacemaker therapy.

Japanese Circulation Journal, 1985
Four hundred and sixty-seven cases with implantation of an artificial pacemaker were studied. The postoperative survival rate was 63% for 15 years. Seventy-two percent of type III patients of the sick sinus syndrome were free from postoperative thromboembolism and the lowest of the three types of the sick sinus syndrome.
