The present invention relates to a non-invasive cardiac monitoring device that records cardiac data to infer physiological characteristics of a human, such as cardiac arrhythmias or other vital signs. Some examples of the invention allow for long-term monitoring of physiological signals. Further examples allow for processing of ECG and PPG data to calculate pulse arrival time. Some examples include a wearable cardiac monitor device on a chest that includes both the ECG and PPG sensor for long-term adhesion to a mammal for prolonged detection of cardiovascular signals.

Adapters, connectors, and tubing provide for connection of a blood pressure cuff to a pressure source, such as a patient cardiac monitor. Adapters, connectors, and tubing are configured to allow a patient to be connected and disconnected from monitoring equipment without removing the blood pressure cuff from the patient's appendage. Among other aspects, adapters may include various configurations that allow connection of: single lumen tubes to single lumen tubes or equipment; single lumen tubes to dual lumen tubes or equipment; dual lumen tubes to dual lumen tubes or equipment; and dual lumen tubes to single lumen tubes or equipment. Tubes may include dual lumen tubing where the lumens are separated by a web, and the web maintains the spacing between the connectors attached to the lumens.
