Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.

<h3>How does the term "intractable pain" mean in medicine?</h3>
The definition of debilitating pain is "hardship whose source can indeed be removed and, per the broadly agreed clinical practice, a wide spectrum of pain treatment modalities adequate for this patient have been used without sufficient result or with unacceptable side effects." When a health care professional certifies a patient as having severe chronic pain, they were also certifying that the patient fulfills this definition.
<h3>An intractable function is what?</h3>
When considering computational complexity, intractable issues are those for which there are no effective solutions. The brute-force search algorithm is the one that offers a solution to the majority of seemingly insoluble situations.

Answer:
Explanation:
Left coronary artery - divides into two branches (the circumflex artery and the left anterior descending artery). Left anterior descending artery (LAD) - supplies blood to the front and bottom of the left ventricle and the front of the septum. Pulmonary veins - bring oxygen-rich blood back to the heart from the lungs.
