“…Device therapies can consume more power than the background operations. Premature (significantly earlier than projected by the manufacturer) device failure due to battery depletion in clinical use is probably mostly driven by the patient's clinical needs for therapy, partially due to suboptimal programming by healthcare professionals, and unlikely to be the manufacturer's fault unless component failure can be clearly identified …”

Introduction The longevity of a cardiac implantable electronic device (CIED) depends on how quickly the powers consumed by the device's functions exhaust its usable battery energy. A mathematical model for CIED power consumptions was developed and validated against longevity data from manufacturers. Methods The programmable parameters for the Resonate X4 cardiac resynchronization therapy defibrillators (CRT‐Ds) on the Boston Scientific (St. Paul, MN, USA) online longevity calculator were designated as independent terms in the sum for the total power consumption. The reciprocal of longevity was plotted against variations in these terms. Linear and nonlinear regression analyses were used to fit the plots. The power consumed by pacing was theoretically derived and used as the calibrating tool for estimating the powers consumed by other functions and the usable battery energy. The same methodology was applied to the longevity data of other manufacturers’ CRT‐Ds. Results Single chamber 100% pacing at 60 beats/min, 2.5 V, 0.4 ms, 500 Ω consumes ≈ 144 J/year. Shock therapy is 45–85% energy efficient. Multichamber pacing modes and maintaining readiness to pace a chamber consume power even if no pacing is delivered. Switching voltage regulation is theoretically more energy efficient than linear voltage regulation for powering pacing. Conclusions The powers consumed by therapy functions are dictated by the patient's clinical needs, but healthcare professionals can extend device longevity by switching off dormant functions and simplifying the pacing mode. Choosing a device model with large usable battery energy, low background power, and energy efficient pacing and shock therapy for implantation will increase the probability of a long service lifespan.

“…Recently, most of the manufacturers of implantable cardiac devices faced problems with lithium plating which randomly can cause rapid battery depletion. Here, activating RM was strictly recommended by the manufacturers and became a beneficial and irreplaceable instrument for both patient and healthcare professional helping to detect affected devices as early as possible [ 15 – 17 ].…”

Purpose of Review This review offers an overview of the evidence in diagnostic and therapeutic applications of remote monitoring implantable devices. Recent Findings Remote monitoring of cardiac implantable devices has become more and more popular in recent years as healthcare is moving towards a more patient centralized system. For heart failure patients with an ICD or pacemaker, there is controversial evidence regarding improvements in the clinical outcome, e.g., reduction of hospitalization rates or overall mortality. New developments as hemodynamic remote monitoring via measurement of the pulmonary artery pressure are promising technical achievements showing encouraging results. In cardiac remote monitoring of syncope and arrhythmias, implantable loop recorder plays an important role in diagnostic algorithms. Summary Although there is controversial evidence according to remote monitoring of implantable devices, its use is rapidly expanding, giving healthcare providers the opportunity to react promptly to worsening of their patients. Adequate evaluation of the data created by remote monitoring systems remains an unsolved challenge of contemporary healthcare services.
