Because air flows throughout the planet, dust and pollution travel across oceans and continents, where pollutants land in sea waters, and on streets, and fall in rain water. Therefore nations must unite to combat the problem together.
According to the research, the p wave on an electrocardiogram (ecg) represents the first wave of the cardiac cycle which is the atrial electrical depolarization.
<h3>What is an electrocardiogram?</h3>
It is the graph that records the electrical activity of the heart and allows the diagnosis of different cardiovascular diseases and helps to know the state of the heart muscle.
It presents a P wave (corresponding to atrial depolarization), a QRS complex (ventricular depolarization), and a T wave (ventricular repolarization).
Therefore, we can conclude that according to the research, the p wave on an electrocardiogram (ecg) represents the first wave of the cardiac cycle which is the atrial electrical depolarization.
