In recent decades, invasive electrophysiological study (ES) has become an important instrument to evaluate patients with conduction disturbance and cardiac arrhythmias. Using catheters placed in heart chambers via central vein and/or central arterial access, ES may...doi:10.1007/978-3-319-92729-9_2Celestino SarduValerio GiordanoAntongiulio D...
Mitral stenosis was estimated to be responsible for 25% of all deaths from systemic embolism when surgery and anticoagulation were not available [27]. While the stroke rate in patients with AF is, on average, approximately six times the stroke risk in people without AF, the relative risk is ...
The lack of available data makes it very difficult to determine the clinical relevance of a certain measurement error in regional strain measurements. We assume, however, that deviations in the range of up to 80% of the correct value must be considered relevant in any case. For global longitud...
moving closer together or on a piezoresistive strain model in which resistors on the diaphragm change their electrical resistance according to the extent of deformation10. The barometer is then able to determine changes in altitude, track stair count and detect falls on the basis of the principle ...
1 and Table 1), followed by ventricular tachycardia (VT) and atrial fibrillation (AF). Fig. 1 The contents of the arrhythmias in the patients who were admitted to the CCU/ICU in the Tokyo CCU Network for the treatment of arrhythmias in 2014. Those correspond to approximately 10% of the ...
Mark out several consecutive R-R intervals on a piece of paper, then move them along the rhythm strip to check if the subsequent intervals are similar. Hint If you are suspicious ofatrioventricularblock(AV block), map out theatrialrateand theventricularrhythmseparately (i.e. mark the P waves...
It remains uncertain whether interventions to lower resting heart rates are beneficial in patients with coexisting AF&CHD. This study aims to determine the optimal level of resting heart rate control in this specific patient group. Methods Database access The current analysis is based on the ...
When testing thyroid function, most physicians order only TSH (thyroid stimulating hormone) and T4. But to have normal thyroid function several conditions must be met. Of those many conditions, three are often not considered by most physicians and not evaluated with TSH and T4. First, there mus...

What are two main things that determine the direction that blood flows through the heart? Give one specific example by describing their role during ventricular ejection. How do the heart valves function to provide unidirectional blood flow? What factors ...
