T wave alternans (TWA) is a periodic beat-to-beat variation in the amplitude or shape of the T wave in an electrocardiogram TWA was first described in 1908. At that time, only large variations could be detected. Those large TWAs were associated with increased susceptibility to lethal ventricular tachycardias.
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It is seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled pericardial sac.
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis.
Kessleria is a genus of moths of the family Yponomeutidae.

The Indotyphlidae are a family of common caecilians found in Africa, Seychelles and India. Like other caecilians, they superficially resemble worms or snakes.
Bigeminal pulse is a medical condition, easily confused with pulsus alternans. Similar features between bigeminal pulse and pulsus alternans are strong peak and weak peak. However, unlike pulsus alternans, the weak beat in bigeminal pulse occurs prematurely (early). Thus, not followed a pause as it is in pulsus alternans but occurs close to normal strong beat.

Physocarpus alternans also known as dwarf ninebark and Nevada ninebark is a flowering shrub native to east California, currently found throughout Western North America. It was first described by J.T.Howell in 1931. It prefers growing on dry, rocky slopes, grows in pinyon and juniper shrublands, also found near limestone outcrops. It has been found to grown at elevations of 1800 to 3100 m above sea level. Aside from the native California specimens have been collected in Nevada, Utah, Idaho and Colorado. It flowers in June and July, producing small, white flowers.
Leptoseris is a genus of corals belonging to the family Agariciidae.
