Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram.

Skin electrode gels are used extensively to reduce electrical resistance when using skin surface electrodes, both for medical instrumentation such as EEG, EMG and EKG, and for electrical stimulation treatments such as TENS, electrotherapy, electroconvulsive therapy and defibrillation.
Each Holter system has hardware (called monitor or recorder) for recording the signal, and software for review and analysis of the record. There may be a "patient button" on the front that the patient can press at specific instants such as feeling/being sick, going to bed, taking pills, marking an event of symptoms which is then documented in the symptoms diary, etc.; this records a mark that ...
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
The technician or physician can download and review the recorded events during an office visit using a special programmer [4] or via online data transmission. [ 5 ] Remote control for a Biotronik implantable loop recorder used by the patient
This mode is usually employed with the probe in physical contact with the skin or lesion to be destroyed. This method is notable for causing relatively little actual destruction at the point of skin contact, but a large zone of destruction beneath the skin, as the current from the probe fans out into the tissue below the point of contact.

Surgical tape or medical tape is a type of pressure-sensitive adhesive tape [1] used in medicine and first aid to hold a bandage or other dressing onto a wound. These tapes usually have a hypoallergenic adhesive which is designed to hold firmly onto skin, dressing materials, and underlying layers of tape, but to remove easily without damaging ...
