The hybrid stimulation system is an electrical stimulation system serves to delivered an electrical stimulation impulse to the heart (human or animal heart) , using a combination of internal (intravascular) and external (body surface) electrodes, the hybrid electrical stimulation system can be used for pacing of the heart during slow heart beat (bradycardia), or shocking the heart during fast heart beat (Tachycardia) , or to terminate fast abnormal heart beat (tachy-arrhythmia) by means of override pacing (Anti-tachycardia pacing). This hybrid system can be used and introduced into the body without the need for imaging guidance such as fluoroscopy or echocardiography to insert the internal component, and does not require direct contact between the internal pacing wire and the myocardium (internal heart surface).

Disclosed are a pacing control method, a pacing control apparatus, and a medical device. The pacing control method comprises: obtaining an actual heart rate of a patient; and when the actual heart rate meets a preset low heart rate condition, performing cardiac pacing on the patient by using a preset pacing frequency, the preset low heart rate condition being used for representing that the patient is in a life-critical state. The method takes the patient in the life-critical state where the heart rate is severely too slow or even cardiac arrest occurs as an object needing pacing support, and achieves the effect of timely and effectively pacing to support the life of the patient and the effect of avoiding, to a great extent, unnecessary pacing for the patient and the pain of the patient caused by pacing stimulation, especially cannot trigger pacing to occasional bradycardia, non-severe bradycardia, or transient arrest.

An implantable leadless pacemaker configured to provide antibradycardia pacing of a human or animal heart, comprising: an electrical energy source, a sensor configured to sense intracardiac potentials of the heart, a pulse generator configured to generate electrical pacing pulses, a control unit for controlling the pulse generator, wherein the control unit is configured to inhibit generation of an electrical pacing pulse when an intracardiac potential is sensed, wherein the control unit is further configured to permanently switch off the pulse generator after passing of a predetermined timespan and / or after a pre-defined event detected by the pacemaker, an electrode pole for electrical stimulation and sensing intracardiac potentials, at least one fastening element for fastening the pacemaker to heart tissue, wherein the implantable leadless pacemaker is adapted such that a lifetime of the implantable leadless pacemaker is smaller than one year, particularly smaller than one month, particularly smaller than two weeks.

Multiple external electrodes are used to monitor cardiac electrical activity from the patient's tissues. One or more cardiac measurements of the patient are generated based on the monitored electrical activity. If the patient has right bundle branch block, the one or more cardiac measurements are used based on a first global synchrony measure to determine whether the patient is a candidate for a cardiac resynchronization therapy (CRT) device. If the patient does not have right bundle branch block, the one or more cardiac measurements are used based on a second global synchrony measure to determine whether the patient is a candidate for a cardiac resynchronization therapy (CRT) device.

A wearable medical system (WMS) includes one or more pacing capabilities. The WMS May detect when the patient's heart rhythm starts to deteriorate, but not necessarily in a way that requires Defibrillation. In particular, the WMS may detect bradycardia of one or more types, and then confirm the detection before pacing to treat the detected bradycardia.

An implantable medical stimulation device (1) for performing an anti-bradycardia pacing in an atrium (RA) of a patient's heart (H) comprises a generator device (12) comprising processing circuitry (120) for processing cardiac sense signals and generating cardiac stimulation signals and a housing (121), and an electrode arrangement for sensing cardiac signals and outputting cardiac stimulation signals. The electrode arrangement comprises at least one atrial electrode pole (102, 103). The processing circuitry (120) is configured to perform a rate-adaptive cardiac stimulation in which a paced heart rate is adjusted based on a load state of the patient, wherein the processing circuitry (120) is configured to obtain a momentary impedance curve (ΔZ1), to compare said momentary impedance curve (ΔZ1) to a stored reference curve (ΔZrefRest) and to perform an adaption of the paced heart rate based on the comparison of the momentary impedance curve (ΔZ1) to the stored reference curve (ΔZrefRest). The processing circuitry (120) is configured to obtain said momentary impedance curve (ΔZ1) by conducting a unipolar impedance measurement between the at least one atrial electrode pole (102) and the housing (121).
