2, the decrease in the rate of depolarization of action potential slows intra ventricular conduction and increases the duration of QRS complex.

Fatal effects of hyperkalemia

Among the techniques suitable to study molecular mobility in very viscous systems, dynamic mechanical spectroscopy, NMR spectroscopy, dielectric relaxation spectroscopy (DRS), and thermally stimulated depolarization currents (TSDC) are the most frequently used.

(PR segment is the interval between the onsets of atrial depolarization and ventricular depolarization.) Prolonged action potential duration (amount of time that voltage remains above threshold) first occurred at 1 [micro]M BPM, and delayed atrioventricular conduction appeared at 10 [micro]M BPM.

Bisphenol A (BPA) and the heart

In 2001, my group and two other laboratories independently reported that depolarization of postsynaptic neurons causes endocannabinoid-mediated transient suppression of transmitter release from presynaptic terminals in the hippocampus and cerebellum.

Control of synaptic function by endocannabinoid-mediated retrograde signaling

Although the latter is primarily attributed to neuronal influences, decreased heart rate variability can also indicate alterations in ion channel currents that drive pacemaker depolarization (Papaioannou et al.

Purpose/Hypothesis: The QT interval is an element of the electrocardiograph (ECG) tracing that includes ventricular depolarization and repolarization and that provides clinical evidence regarding ventricular function.

Physical activity, BMI and smoking history affect qt interval duration in cardiac patients

The QT interval encompasses both depolarization and repolarization of heart and was measured from the earliest Q- or R-wave onset to the end of T wave.
