<span>A mineral has to be naturally occurring, inorganic, solid, have a crystal structure, and have a definite chemical composition. Coal is not a mineral because it is carbon-based and came from fossilized plants. That proves that it is organic and has no definite chemical composition, defying two rules you would need to follow to be a mineral. Glass is a non-crystalline solid. This means that the atoms are not arranged in a regular and repeating pattern. A mineral by definition possess a crystalline form, it has its elements arranged in a regular and repeating pattern.</span>

Which component of the electrocardiogram represents the duration of ventricular contraction?
Advocard [28]

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.
