“…1 Other unique written and video-documented accounts of extracardiac muscle activation from device/lead defects have been reported. 2 , 3 However, these were further characterized by corresponding maladies in lead integrity metrics or grossly visible hardware flaws, which were not identified in our case. Pectoral capture as a cause of debilitating postural “palpitations” can occur owing to lead integrity failures despite stable lead parameters on interrogation.…”

“…The pacemaker will be part of the patient's life expectancy and, therefore, the assessment of patient and caregiver knowledge is important to prevent early complications and dysfunction and that immediate treatment can be provided (Hatchett & Thompson, 2002). The pacemaker is also reported to induce musculoskeletal attention of the diaphragm, the pectoral or the intercostal muscles due to normal extracardiac stimulation (Rasmussen & Pareek, 2014). The implantation of pacemaker is also reported in reducing the incidence of falls, fall-related fractures and fall-related injuries among patients with sinus node dysfunction (Brenner et al, 2017).…”

Introduction: The number of patients with pacemaker implant is increasing in the health services sector in Malaysia, which requires nurses to have expertise in patient care with pacemaker implantation. Therefore, this study was conducted to analyse the level of knowledge among nurses regarding the management of patients with pacemaker implantation.Methods: A cross-sectional study was conducted through purposive sampling among all nurses working at the critical care unit, intensive care unit, cardiac rehabilitation ward, investigation clinical laboratory, and non-invasive clinical laboratory in a public hospital in Kelantan. A questionnaire consisted of demographic data and nurses’ knowledge was distributed. Data were analysed for descriptive analysis and using Pearson correlation test.Results: Results from all respondents (n=70), show 48.6 % of the respondents had moderate knowledge about patient management with pacemaker implantation, 32.9 % had a low level of knowledge and only 13.6% had high knowledge regarding management of patient with pacemaker implantation. There is a significant difference between the level of knowledge and demographic data, that is between the level of education (p=0.027), age (p=0.011) and length of service (p=0.015). There is no significant relationship between knowledge and demographic data, such as gender (p=0.481), marital status (p=0.315), and post-basic (p=0.067).Conclusion: Level of knowledge among nurses about the management of patient with pacemaker implantation is low to moderate. Additional education and exposure among nurses are needed to enhance the knowledge of nurses and improve the quality of care among patients with pacemaker implant.

In cardiac pacemaker design, energy expenditure is an important issue. This work aims to explore whether varying stimulation pulse configuration is a viable optimization strategy for reducing energy consumption by the pacemaker. A single cardiomyocyte was used as an experimental model. Each cardiomyocyte was stimulated with different stimulation protocols using rectangular waveforms applied in varying number, in short succession. The amplitude, the width of each pulse, and the interval between consecutive pulses were modified. The application of multiple pulses in a short sequence led to a reduction of the threshold voltage required for stimulation when compared to a single pulse. However, none of the employed multi-pulse sequences reduced the overall energy expenditure of cell stimulation when compared to a single pulse stimulation. Among multiple pulse protocols, a combination of two short pulses (1 ms) separated with a short interval (0.5 ms) had the same energy requirements as a single short pulse (1 ms), but required the application of significantly less voltage. While increasing the number of consecutive pulses does not reduce the energy requirements of the pacemaker, the reduction in threshold voltage can be considered in practice if lower stimulation voltages are desired.
