Lead I of an electrocardiogram (ECG) views the electrical activity of the heart primarily from the left side. Specifically, it measures the voltage difference between the right arm (negative electrode) and the left arm (positive electrode), providing a perspective on the left atrium and left ventricle. This lead helps assess the heart's overall rhythm and can indicate issues related to the left side of the heart.

Beta-1 refers to the beta-1 adrenergic receptor, which is a type of receptor found in the heart and kidneys that plays a role in regulating heart rate and blood pressure. Activation of beta-1 receptors can lead to an increase in heart rate and force of contraction in the heart. Medications that target beta-1 receptors are commonly used to treat conditions such as high blood pressure and heart failure.
the two kinds of large veins are: 1. superior vena cava- upper part of the heart 2. inferior vena cava- lower part of the heart
