Other devices exist to occlude the left atrial appendage from the inside of the heart such as the Wavecrest device [24] and the Lariat device. [25] The latter technique entails closing a strangling noose around the LAA, which is advanced from the chest wall with a special sheath, after introducing a balloon in the LAA from the inside surface of ...
An implantable loop recorder (ILR), also known as an insertable cardiac monitor (ICM), is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period.
In a small number of cases left ventricular assist devices, combined with drug therapy, have enabled the heart to recover sufficiently for the device to be able to be removed (explanted). [ 7 ] [ 8 ] Several surgical approaches, including interventional decommissioning, off-pump explantation using a custom-made plug and complete LVAD removal ...
The device is approved for use in high-risk percutaneous coronary intervention (PCI) and cardiogenic shock following heart attack or open heart surgery and is placed through a peripheral artery. [2] From the peripheral artery it pumps blood to the left or right heart via the ascending aorta or pulmonary artery .
Ventricular escape beats occur when the rate of electrical discharge reaching the ventricles (normally initiated by the heart's sinoatrial node (SA node), transmitted to the atrioventricular node (AV node), and then further transmitted to the ventricles) falls below the base rate determined by the rate of Phase 4 spontaneous depolarisation of ventricular pacemaker cells.

Future care could use heart data from mobile devices to ensure timely access to medical care. Additionally, monitoring heart conditions could help assess how well treatments work. [17] Many people worry when they feel palpitations. [1] However, in most cases, the cause of palpitations is harmless, so detailed medical tests are often not needed. [1]
More modern devices have software designed to attempt a discrimination between ventricular fibrillation and ventricular tachycardia (VT), and may try to pace the heart faster than its intrinsic rate in the case of VT, to try to break the tachycardia before it progresses to ventricular fibrillation. This is known as overdrive pacing, or anti ...
The FDA approved the CardiAssist ECP system for the treatment of angina, acute myocardial infarction and cardiogenic shock under a 510(k) submission in 1980 [1] [failed verification] Since then, additional ECP devices have been cleared by the FDA for use in treating stable or unstable angina pectoris, acute myocardial infarction, cardiogenic shock, and congestive heart failure.
