Electrode arrangement for a curvilinear medical device lead

A method comprising:

• sensing, by sensing circuitry, a first electrogram according to a first vector including a first low voltage electrode and a second low voltage electrode, wherein the first electrogram provides a first angular perspective of a directional cardiac depolarization of a heart of a patient,
• wherein a medical electrical lead comprises:
• 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 between the proximal coated portion and the distal coated portion;
• and
• a set of low voltage electrodes positioned on the lead body, the set of low voltage electrodes comprising the first low voltage electrode and the second low voltage electrode distal to the first low voltage electrode;
• and
• sensing a second electrogram according to a second vector including one of the first low voltage electrode or the second low voltage electrode and the uncoated portion, wherein the second electrogram provides a second angular perspective of the directional cardiac depolarization of the heart of the patient,
• wherein the first angular perspective of the directional cardiac depolarization is different than the second angular perspective of the directional cardiac depolarization, wherein an angle between the first vector and the second vector is within a range from thirty degrees to sixty degrees, causing the first angular perspective to be different than the second angular perspective.
