  • Atrial fibrillation is the commnest arrhythmia in the elderly. However, the quality of life in the patients with atrial fibrillation are not investigated in Japan. We investigate the factors that influence the QOL in the patients with atrial fibrillation.
  • The clinical features of ventricular arrhythmia and RR-interval dynamics in AF-patients remain unresolved. We successively plotted points on an X-Y plain as (X, Y)=(RRn, RRn+1) from the consecutive RR-intervals of Holter ECGs. Eighty out of 175 AF-patients were thus diagnosed to have ventricular arrhythmia based on the different plotting patterns between ventricular premature contractions (VPCs) and aberrations. Different characteristics of the RR-interval dynamics before VPCs were observed such as fixed or variable coupling, and a regular or irregular RR-interval sequence. Malignant arrhythmias occurred more frequently in AF-patients with variable coupling VPCs and/or an irregular RR-interval sequence before VPCs than in those with the fixed coupling VPCs and /or the regular RR-interval sequence before VPCs. The RR-interval plotting method enabled us to distinguish different types of VPCs which were related to the clinical characteristics of the AF-patients.
  • In Japan, hot tub is very popular from the young to the elderly. However, more than 10,000 elder people die annually during or after hot tub immersion. Yet the definite causes of those deaths have not been fully understood. Thus, we investigated the effects of hot tub immersion to the elderly especially regarding to cardiopulmonary functions. We studied 12 apparently healthy elder volunteers (6 males, 70±5 y). They took the bath of different temperature (41°C, 38°C) on the separate days. We assessed the changes of blood pressure (BP), pressure-rate product (PRP), oxygen saturation (Spo2), tympanic temperature (Ttymp), and Holter ECG. In 38°C-bath immersion, none of the cardiopulmonary indices changed significantly. In contrast, 41°C-bath immersion significantly increased BR, PRP, and Ttymp, suggesting hot tub with higher temperature may give more stress to the cardiopulmonary system. To elder people with diseases, higher hot tub immersion would affect much more than to healthy or younger people.
Current and Past Project
  • We register the patients with syncope all over Japan for 3 years and define the characteristics of the patients.
  • To obtain the fact of suitable treatment of atrial fibrillation in Japan, the Japanese Society of Electrocardiology conducts the randamized trial between the treatment of maintaining the sinus rhythm and the rate control of atrial fibrillation.

2. Clinical characteristics and treatments of atrial fibrillation in hyperthyroidism
Hyperthyroidism is well known pathophysiological status that atrial fibrillation (AF) is frequently observed. We investigated the clinical characteristics of 677 hyperthyroid patients (female: 519, average age: 41y.o.) and had 11.1% (chronic: 4.6% and paroxysmal: 6.4%) of AF. The average age of the AF patients (54y.o.) was significantly higher than that of sinus rhythm patients (38y.o.). The significant factors related to the occurrence of AF were firstly the period of untreated hyperthyroidism and secondly the onset-age of the hyperthyroidism. The history of congestive heart failure (CHF), the enlarged cardiothoracic ratio, enlarged left atrial diameter and left ventricular diameter, and severe mitral and/or tricuspid regurgitation were observed more frequently in chronic AF than in sinus rhythm. In paroxysmal AF, the episodes of the recurrence of hyperthyroidism due to the difficulties of the ordinary treatments or the dropout of the treatment of hyperthyroidisim were the main factor of the occurrence of paroxysmal AF. The use of antiarrhythmic drugs such as pilsicainide was useful in the termination of paroxysmal AF but not in that of chronic AF. The most important strategy of the prevention of AF in hyperthyroidism is early treatment of hyperthyroidism especially in the elder patients.
