Heart rate monitor for an aerosol delivery device

A control body coupled or coupleable with a cartridge to form an aerosol delivery device, the cartridge being equipped with a heating element and containing an aerosol precursor composition, the control body comprising:

• a housing;
• a microprocessor configured to operate in an active mode in which the control body is coupled with the cartridge, the microprocessor in the active mode being configured to control the heating element to activate and vaporize components of the aerosol precursor composition;
• and
• a heart rate monitor including a plurality of biopotential electrodes affixed to the housing and configured to obtain biopotential measurements from a user, and including signal conditioning circuitry configured to produce an electrocardiogram signal from the biopotential measurements,
• wherein the microprocessor is coupled to the signal conditioning circuitry and further configured to control operation of at least one functional element of the control body or the aerosol delivery device based on the electrocardiogram signal or a heart rate of the user calculated therefrom.
