Average heart rate

Average heart rate (24h, daytime,nighttime) on a smoking and a nonsmoking day persisting tachycardia... 

The average heart rate is 75 beats/min. How many times does the avetage petson s heart beat in a week ... 

Congenital 3rd degree AV block beyond 1 year of age with average heart rate < 50, abrupt pauses in ventricular rate of 2-3 times the basic cycle length, or associated with symptoms due to chronotropic incompetence... 

These results indicate that the dependency of image quahty on the average heart rate decreases with the increasing temporal resolution of the CT scanners. Another conclusion from these studies is that until the use of 64-shce CT for noninvasive coronary imaging, the administration of (3-receptor antagonists is advisable when the heart rate exceeds a certain threshold (60 or 65 bpm). With dual-source CT, heart rate control through the use of beta-blockers is no longer required (Fig. 15.2).

In 33 patients (30 men, median age 52 years) the most common effects of poisoning with mad honey were sinus bradycardia (91%), nausea and vomiting (82%), and dizziness (79%) average heart rate was 55/minute and mean blood pressure was 78/46 mmHg [107"]. 

The model structure is shown in Fig. 18.13, for reasons of simplicity a constant stroke volume of 75 ml is assumed in the simulation. The variation in heart rate is shown in Fig. 18.14. It can be seen that the average heart rate is about 62 beats/min, fluctuations are in the order of 10 beats/min. 

The thinner curve with peaks is showing immediate heart rate and the thicker curve is showing average heart rate. 

The second window is showing heart tachogram window. Here are several curve, immediate heart rate, average heart rate, mean value and physiological and morbid bound of heart rate.

Tachycardia An abnormally rapid beating of the heart, defined as a resting heart rate over 100 beats per minute in an average adult. 

An average adult at rest may have a heart rate of 70 beats per minute and a stroke volume of 70 ml per beat. In this case, the cardiac output would be ... 

In the early 1970s, cannabis was noted to reduce intraocular pressure in people with glaucoma (Cooler and Gregg 1977). In a controlled study, THC decreased intraocular pressure an average of 37%, with maximum decreases at 51% of baseline. Concurrent increases in heart rate were also observed. The mechanism of this effect of THC is uncertain. 

John s response to 7 mcg/kg of BZ was longer in duration than the average, as can be seen by comparing the expected with the actual scores on NF as well as the somewhat higher heart rate. When retested two weeks later, he received physostigmine repeatedly and after the first few hours, his NF scores and heart rate measurements were maintained close to the baseline values. 

Duration of observation (Table 6) for each subject was lengthy and required a total more than 300 subject days of testing, considering that each subject (in groups of 2-4 as a rule) occupied a test cubicle for an average of five days. Vital signs, including pupil size, heart rate, blood pressure and performance on NF and VITA, were measured at 1, 2, 3, 4, 6, 8, 10, 12, 16 and every four hours thereafter until recovery. The nurse entered full descriptions of behavior as often as possible. 

Figure 75 indicates the linear relationship between the LDso in the mouse and the HRso (average dose sufficient to raise the human heart rate to 100 beats per minute). Only five belladonnoids are shown because of insufficient data for the other agents. 

Because of the extensive presence of )Si-ARs in the non-failing myocardium, the heart can be defined as a jSi-AR organ. The )Si// 2-AR ratio within the ventricles of the healthy human heart is 80/20 and the average jS-AR density (Bmax) in atria and ventricles is normally 70-100 fmol/mg protein [89], In the heart, Pt-AR agonists are responsible for the increase in cardiac contractility and heart rate, whereas bronchodilation and vasodepression can be mediated by / 2-selective agonists.
