Eine gestörte Repolarisation mit verlängerter QT-Zeit im Oberflächen-EKG und verlängertem Aktionspotential auf zellulärer Ebene gilt als Ursache potentiell lebensbedrohlicher ventrikulärer Arrhythmien. Das angeborene Long-QT-Syndrom wurde in diesem Zusammenhang lange als Rarität an...
Congenital long QT syndrome (LQTS) is an inherited condition that affects heart muscle cells and predisposes individuals to potentially fatal ventricular arrhythmias. This condition manifests (usually) with a prolonged time interval between the Q and T waves of the EKG and the occurence of either s...
This is manifested on the electrocardiogram (ECG, EKG) by a prolonged QT interval. “QT prolongation”, or a prolonged QT interval, makes the heart vulnerable to polymorphic ventricular tachycardias, one kind of which is a fast, abnormal heart rhythm known as Torsade de Pointes. The corrected...
Despite differences in drug class and chemical structure of compounds that block hERG, a common explanation for the effect of pH on drug potency has emerged, based on how charge on the functional groups of a drug molecule affects their partition coefficients and hence their ability to cross the ...

EKG was performed on 91 patients, comprising 60 with a mild form and 31 with a medium form of the disease (Table 4). There were no statistically significant differences observed in the analysis of the amplitude and duration of the P wave, PR interval, QRS duration, RT duration at baseline...
layer of the skin, which causes weak conductivity between the electrodes and the skin. This can be seen in ECGs acquired with the Arduino device with which, on top of having some noise, one can see a kind of biphasic T-wave which is in fact an artifact coming from the Arduino analog ...
When it is unclear if U waves are present, inspection of neighboring leads on the ECG may be helpful in separating a discrete U wave from the T wave. ➢ Bifid T waves: T waves may be notched or bifid in appearance and the end of the T in these cases should be measured after the...
WSN scalability is dependent on reduced costs and long-term deployment without battery replacement. The urgency of this topic is evident because in the present year of 2017, the predictions point to 28.8 billion IoT devices, a number that is expected to almost double in three years, as seen ...
