question 207

Multiple Choice

On a normal ECG, a wave for repolarization of the atria is not recorded.Why

• A)The leads are not placed in a position to pick it up.
• B)No repolarization of the atria occurs normally.
• C)It occurs simultaneously with ventricular depolarization and is masked by the QRS complex.
• D)It does not travel through body fluids.

Definitions:

Load Resistor

A resistor used in a circuit primarily to replicate the load that a transducer or other device would exert on the circuit.

Wye-Connected

A method of connecting three-phase circuits where the ends of each phase are connected to a common point, forming a shape similar to the letter "Y".

Phase Voltage

The voltage measured in a single phase of a three-phase system, indicative of the electric potential difference in that phase.

Delta-Connected

Refers to a specific way of connecting three-phase electrical devices where the ends of each component are connected in a triangular loop, allowing for balanced loads.
