The human sinoatrial node (SAN), the main pacemaker of the heart, has redundant, fail-safe mechanisms that maintain a consistent heart rhythm and protect the heart from rhythm failure even under stress conditions, according to a new study published in Science Translational Medicine . "[We found...
Instead of adding a dual-chamber pacemaker to the single-chamber ICD, physicians often reduce the medication doses to prevent single-chamber right ventricular stimulation. Cardiac output is increased in proportion to heart rate, and atrial pacing has been shown to reduce the incidence of atrial ...
If the fuel cell engine is compared to the "heart", the hydrogen circulation system is the "pacemaker", which is used to assist in the efficient circulation of hydrogen to achieve the best possible power output. The fuel cell engine hydrogen circuit works in a return pump and pilot mode. ...
There was significantly more hemodynamic support (Impella; Abiomed, Danvers, MA) and temporary pacemaker utilization in the TFA group (Table 3). Also, in the TFA group, the pre-procedural diameter stenosis was significantly higher (85.6% vs. 82.9%, p = 0.015) and the resulting post-...
A pacemaker programmer and diagnostic system retrieves information stored within a pacemaker and analyzes the retrieved data in real time. The stored information can be retrieved by means of a telemetry communication link. The pacemaker automatically lengthens an AV delay. The pacemaker determines atrial...
