Ca²⁺ transient abnormality types. Normal = N; oscillation = OS; multiple peak = MP; alternans = AL; plateau abnormality = PA; low peaks = LP; and irregular phase = IP. Multiple peaks is two or three consecutive peaks where the amplitude does not decay to the baseline, and oscillation is more than three consecutive kinds of these peaks.
