Which component of the electrocardiogram represents the duration of ventricular contraction?

Biology

Advocard [28]2 years ago
5 0

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Why does coomassie brilliant blue r interact differently with different proteins?
alexandr1967 [171]
Dimethyl sulfoxide was found to be effective for extraction of Coomassie Brilliant Blue R-250 (Coomassie R) from stained proteins on polyacrylamide gel slices. A good correlation was found between the ability of different proteins to bind Coomassie R and their capacity for interaction with Coomassie Brilliant Blue G-250 (Coomassie G) in solution. Scatchard analysis showed that the number of Coomassie R ligands bound to each protein molecule is approximately proportional to the number of positive charges on the protein, about 1.5-3 dye.
