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.

Answer:
The Diathesis-Stress Model explains that psychological disorders derive from the combination of a predisposition to vulnerability or diathesis, as an innate factor, together with experiences of stress as an acquired factor. Therefore, innate factors and acquired factors are needed to develop certain disorder.
Explanation:
From the perspective of the diathesis-stress model, a disorder is the result of the interaction between a genetic predisposition or vulnerability (diathesis), with external factors or personal experiences (stress). This model is used to explain the development of mental disorders with a clear genetic basis, such as schizophrenia, bipolar disorder, etc. The appearance of the disorder will depend on the combination of both factors. The more genetic predisposition you are, the more likely you are to develop these low-stress diseases. And on the contrary, a low predisposition protects us from suffering a mental disorder, even if different stressors occur in our life.
