An implantable stimulator and monitor measures a group of heart failure parameters indicative of the state of heart failure employing EGM signals, measures of blood pressure including absolute pressure P, developed pressure (DP=systolic P-diastolic P), and / or dP / dt, and measures of heart chamber volume (V) over one or more cardiac cycles. These parameters include: (1) relaxation or contraction time constant tau (.tau.); (2) mechanical restitution (MR), i.e., the mechanical response of a heart chamber to premature stimuli applied to the heart chamber; (3) recirculation fraction (RF), i.e., the rate of decay of PESP effects over a series of heart cycles; and (4) end systolic elastance (E.sub.ES), i.e., the ratios of end systolic blood pressure P to volume V. These heart failure parameters are determined periodically regardless of patient posture and activity level. The physician can determine whether a particular therapy is appropriate, prescribe the therapy for a period of time while again accumulating the stored patient data for a later review and assessment to determine whether the applied therapy is beneficial or not, thereby enabling periodic changes in therapy, if appropriate. Drug therapies and electrical stimulation therapies, including PESP stimulation, and pacing therapies including single chamber, dual chamber and multi-chamber (bi-atrial and / or bi-ventricular) pacing can be delivered. In patient's prone to malignant tachyarrhythmias, the assessment of heart failure state can be taken into account in setting parameters of detection or classification of tachyarrhythmias and the therapies that are delivered.

Transcutaneous Electrical Nerve Stimulation (TENS), a method of stimulating nerves using electrical current applied through the skin for therapeutic purposes, has been in use since the late 1970's, as have electronic units for self-administration of TENS therapy. With the recent increase in popularity of mobile devices capable of audio playback (smart phones, portable computing devices, MP3 players etc.), most TENS users already carry consumer electronic equipment capable of providing power and control to another device via its audio port. A TENS unit designed to: (a) be coupled with an audio playback capable device, (b) make use of its power and (c) rely on it for user interaction, provides a smaller, less expensive and more convenient portable treatment solution. This approach can be extended to other electrotherapy forms utilizing similar power budgets: Microcurrent Electrical Nerve Stimulation (MENS), Percutaneous Tibial Nerve Stimulation (PTNS), Electrical Muscle Stimulation / Neuromuscular Electrical Stimulation (EMS / NMES).
