This disclosure is directed to a curvilinear medical electrical lead. For example, a medical electrical lead includes a lead body, a high voltage electrode positioned on the lead body, the high voltage electrode comprising a proximal coated portion, a distal coated portion, and an uncoated portion. Additionally, the medical electrical lead includes a first low voltage electrode and a second low voltage electrode distal to the first low voltage electrode, wherein a first line passes through the first low voltage electrode and the second low voltage electrode, wherein a second line passes through the first low voltage electrode and the uncoated portion, the second line forming a first angle with the first line, and wherein a third line passes through the second low voltage electrode and the uncoated portion, the third line forming a second angle with the first line.
