A 50-year-old lady was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Twelve-lead Electrocardiogram (ECG) was normal during sinus rhythm. The electrophysiological study showed an Atrio-Hisian (AH) interval of 104 ms and Hisio-...
Figure 1. (A) When the T-wave morphology is normal, the T-wave offset is identified when the descending limb returns to the TP baseline; (B) when the T wave is followed by a distinct U wave, the T-wave offset is identified when the descending limb of the T wave returns to ...
To be useful, that predictive model is then deployed—either in a production IT environment feeding a real-time transactional or IT system such as an e-commerce site or to an embedded device—a sensor, a controller, or a smart system in the real-world such as an autonomous vehicle. ...
The set builder notation {x|x is less than or equal to 4} reads as x such that x is less than or equal to 4, so we are talking about all of the numbers that are less than or equal to 4, or all numbers from negative infinity to 4, including 4...
What is the net movement of Na^+? Indicate the electrical events that produce each of these waves: a.) P-wave. b.) QRS wave. c.) T wave. Hydropower uses the ___ energy of water to generate electricity. a.) nuclear b.) potential c.) static d.) kinetic Which is an...
Longitudinal strain reflects coiling downward of the oblique helical spiral fibers to generate the normal ~60% ejection fraction [13]. Conversely, short axis shortening arises from predominantly circumferential fiber deformation, but only a ~30% ejection fraction is yielded [13]. These fiber ...
Variations in menstrual cycles may be unrecognised, and questions about ‘What is normal?’ were the most frequently-raised in a study of reproductive anatomy knowledge among young adults in New Zealand (Jackson, 2020). Ovulation is particularly elusive because it is difficult to self-detect (...
Acute heart failure (AHF) is a major burden disease, with a complex physiopathology, unsatisfactory diagnosis, treatment and a very poor prognosis. In the last two decades, a number of drugs have progressed from preclinical to early and late clinical development, but only a few of them have ...
What is the normal rate of a heartbeat? How does the interval between the second sound of one heartbeat and the first sound of the subsequent heartbeat compare to the interval between the first and second sounds of a single heartbeat? In listening to the heart sounds, the duration...
