Cardiac frequency, obtained by M-mode echocardiography and automatically estimated by the cardiac calculation software, declines as gestation progresses and increases during activity, with accelerations of 25 to 40 beats per minute (bpm) of approximately 30 seconds duration.
This finding means that 25% of the decisions in carrying out the pass were influenced by the responses of the autonomous nervous system (for example, cardiac frequency, sweating, muscle tension and body temperature) directed at the stressor event (for example, the semifinals of the Pernambuco under-17 category soccer championship).
Number of red cells units transfused, hemodynamic parameters such as cardiac frequency and mean arterial pressure at admission, and recurrence of AVB were recorded.
The prolongation with more than 450 msec of the QTc interval (QT corrected depending on the cardiac frequency) exposes to the risk of polymorph ventricular arrhythmia known under the name of peak torsade, with an electrocardiographic aspect of twisting of the QRS complexes morphology along the isoelectric line.
I have verified a number of anthropometric indices such as size, weight and span, a number of physiological indices: respiratory frequency, cardiac frequency, vital capacity.
The observed cardiac rhythmic characteristics and parameters were: cardiac frequency, duration and amplitude of P wave, interval PR and QRS duration, amplitude of R wave, interval QT duration, polarity characteristic of T wave, presence or absence of segment ST depression, and the value in grade of QRS mean axis from I and III derivations.
Noting that the cardiac signal is superimposed to the respiratory signal [19], it is possible to look for the cardiac frequency also.
The cardiac frequency was recorded via a heart rate monitor.
This study had the intention to evaluate the cardiac frequency in response to intermittent progressive tests, T-car and Yo-Yo IRT1, through the determination of the variables associated with the deflection point of the cardiac frequency throughout the variables determination associated to the deflection point at the cardiac frequency.
In the normal fetal heart rate range (110-160 bpm), a time variability of 4 ms corresponds to a cardiac frequency variability of 0.81 bpm, while a time variability of 2.6 ms corresponds to a cardiac frequency variability of 0.53 bpm (the values of 0.53 bpm and 0.81 bpm are obtained as follows: 60/(60/110-2.6 ms)-110 = 0.56 bpm and 60/(60/110 - 4.0 ms) - 110 = 0.81 bpm, resp.).
Vallortigara asserted that in contrast, a dog looking to a dog wagging with a bias to the left-and thus showing right-hemisphere activation as if it was experiencing some sort of negative/withdrawal response-would also produce anxious and targeting responses as well as increased cardiac frequency.
The effect of EOAs on the isometric contractions and cardiac frequency in virro was examined.
