Advancement of telemedicine in Africa and the current laws: A case study of Nigeria.

Advancements in technology have heralded more than a few cutting-edge benefits. Medicine is a vital sector of every nation and it has benefitted from these advancements in delivering health care services at a distance. The increasing use of Information and Communication Technology (ICT) by a vast population worldwide has been pivotal for telemedicine in recent years. Many developed and developing countries of the world have embraced telemedicine as a proactive means of delivering health care services to their citizens, although at different rates of development. The challenges associated with health care service and delivery is numerous and telemedicine has become one solution to counter some of these challenges. This paper seeks to examine the state of telemedicine in Nigeria. It identifies the gaps that ought to be filled in the Nigerian legal system and proposes relevant policies and legislation that must be formulated by government alongside appropriate authorities in order to ensure an optimum telemedicine system that meets the standards of conventional medicine.

Evaluation of the indications and arrhythmic patterns of 24 hour Holter electrocardiography among hypertensive and diabetic patients seen at OAUTHC, Ile-Ife Nigeria.

BACKGROUND: There are very limited published studies in Nigeria on the use of 24 hour Holter electrocardiogram (Holter ECG) in the arrhythmic evaluation of hypertensive and diabetic patients. OBJECTIVE: To evaluate indications, arrhythmic pattern of Holter ECG, and heart rate variability (HRV) among patients with hypertensive heart disease (HHD) with or without heart failure and type 2 diabetes mellitus (T2DM) seen in our cardiac care unit. METHODS: Seventy-nine patients (32 males and 47 females) were studied consecutively over a year using Schiller type (MT-101) Holter ECG machine. RESULTS: Out of the 79 patients, 17 (21.5%) had HHD without heart failure, 33 (41.8%) had HHD with hypertensive heart failure (HHF), while 29 (36.7%) were T2DM patients. The mean (standard deviation) ages of HHD without heart failure, HHF and T2DM patients were 59.65 (±14.38), 65.15 (±14.30), and 54.66 (±8.88) respectively. The commonest indication for Holter ECG was palpitation (38%), followed by syncope (20.3%). Premature ventricular contraction was the commonest arrhythmic pattern among the 79 patients, especially among HHF patients. The HRV using standard deviation of all normal-normal intervals was significantly reduced in T2DM patients (81.03±26.33, confidence interval [CI] =71.02-91.05) compared to the HHD without heart failure (119.65±29.86, CI =104.30-135.00) and HHF (107.03±62.50, CI =84.00-129.19). There was a negative correlation between the duration of T2DM and HRV (r=-0.613). CONCLUSION: Palpitation was the commonest Holter ECG indication and premature ventricular contractions were the commonest arrhythmic pattern among our patients. HRV was reduced in T2DM patients compared with hypertensive patients.
