Why is the T wave positive in the ECG?
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
As a wave of electrical depolarization moves parallel to the direction of a lead if it moves towards the positive pole of the lead a?
positive deflection is recorded on the ECG, while if it moves towards the negative pole, a negative deflection is recorded.
When is the heart described as showing arrhythmia or dysrhythmia?
when time intervals between waves, or the order or the number of waves do not fit the normal pattern described above. Other features that may be altered include the direction of wave deflection and wave widths
A in a transverse wave corresponds to a compression in a longitudinal wave?
In a transverse wave, the crest corresponds to a compression in a longitudinal wave.
Which letter corresponds to the trough of the wave?
The letter "B" corresponds to the trough of the wave.
What are Q R and S wave?
Q, R, and S waves are components of the QRS complex in an electrocardiogram (ECG), which represents the electrical activity of the heart during ventricular depolarization. The Q wave is a small negative deflection, the R wave is a large positive deflection, and the S wave is a negative deflection that follows the R wave. Together, these waves indicate the heart's response to electrical signals and are crucial for diagnosing various cardiac conditions. The QRS complex typically lasts between 0.06 to 0.10 seconds in a healthy individual.
What are the basic types of wave interaction?
deflection
Which letter corresponds to the crest of the wave?
The peak of the wave corresponds to the crest, which is represented by the highest point of the wave's oscillation.
What is the characteristic of a sound wave that corresponds to loudness?
The bigger the troughs of the sound wave and height of the wave corresponds to the loudness the higher the wave the louder the sound.
The portion of the ECG that corresponds to atrial depolarization is the?
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
What are four basic types of wave interactions?
deflection
Which letter corresponds to the amplitude of the wave?
The letter "A" typically corresponds to the amplitude of a wave. Amplitude represents the maximum displacement of a wave from its resting position.
