Artificial Pacemakers [PDF]

open access: yesCirculation, 1973
The development of artificial pacemakers for the electrical control of the cardiac rhythm has greatly enhanced the physician's ability to treat cardiac dysrhythmias. Pacemakers have been useful in treating Stokes-Adams syndrome and symptomatic bradyeardias; they have helped control the occurrence of tachyarrhythmias and have played an important role in

Investigating the flow dynamics in the obstructed and stented ureter by means of a biomimetic artificial model. [PDF]

open access: yes, 2014
Double-J stenting is the most common clinical method employed to restore the upper urinary tract drainage, in the presence of a ureteric obstruction. After implant, stents provide an immediate pain relief by decreasing the pressure in the renal pelvis (P)

Experimental analysis and computational modeling of interburst intervals in spontaneous activity of cortical neuronal culture [PDF]

open access: yes, 2011
Rhythmic bursting is the most striking behavior of cultured cortical networks and may start in the second week after plating. In this study, we focus on the intervals between spontaneously occurring bursts, and compare experimentally recorded values with

The Total Artificial Heart and the Dilemma of Deactivation [PDF]

open access: yes, 2016
It is widely believed to be permissible for a physician to discontinue any treatment upon the request of a competent patient. Many also believe it is never permissible for a physician to intentionally kill a patient.

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

The relation between cardiac 123I-mIBG scintigraphy and functional response 1 year after CRT implantation [PDF]

open access: yes, 2020
Cardiac resynchronization therapy (CRT) is a disease-modifying therapy in patients with chronic heart failure (CHF). Current guidelines ascribe CRT eligibility on three parameters only: left ventricular ejection fraction (LVEF), QRS duration, and New ...

In Synch but Not in Step: Circadian Clock Circuits Regulating Plasticity in Daily Rhythms [PDF]

open access: yes, 2016
The suprachiasmatic nucleus (SCN) is a network of neural oscillators that program daily rhythms in mammalian behavior and physiology. Over the last decade much has been learned about how SCN clock neurons coordinate together in time and space to form a ...

Time representation in reinforcement learning models of the basal ganglia [PDF]

open access: yes, 2013
Reinforcement learning (RL) models have been influential in understanding many aspects of basal ganglia function, from reward prediction to action selection.

Wireless Charger for Artificial Pacemaker [PDF]

open access: yes, 2021
The vast majority of the modernized implantable devices and Bio-sensors are set inside a patient’s body. To overcome this constraint, in this paper we have designed a rechargeable battery with wireless power transfer technique. The transdermal power transfer for the Pacemaker which is placed inside the heart should be possible by the concept of mutual ...
