Alteration in Pulse
1. Tachycardia: Excessively fast rate over 100beats per minute in an adult.
2. Bradycardia: a heart rate in an adult of less than 60 beats per minute in an adult
Alteration in Rhythm
3. Dysrhythmia / arrhythmia: a pulse with an irregular rhythm
4. Intermittent pulse: is one in which the beats are missed at regular intervals
5. Pulse deficit: difference between the apical and the radial pulse
6. Extra systoles: When cardiac contractions occur prematurely is called extra systolic pulse. (ectopic beat )
7. Atrial fibrillation: rapid contraction of atrium causing irregular contraction of ventricles.
8. Ventricular fibrillations: Rapid twitching (uncoordinated contraction) of the ventricles.
9. Sinus arrhythmia: Condition in which the pulse rate is rapid during inspiration and slow during expiration.
10. Dicrotic pulse: there is one heart beat and two arterial pulsations giving the sensation of double beat.
Alteration in Pulse Volume
1. Water Hammer Pulse or Corrigans Pulse or collapsing pulse: Rapidly collapsing pulse occurring in aortic regurgitation or incompetence, where the blood having been
forced into artery by the ventricular contraction,
regurgitates back into the ventricle
2. Bounding Pulse: Signifies stroke volume as seen in exercises, anxiety, anemia
3. Pulsus alternans: the rhythm is regular but the volume has an alterative strong and weak character. This may be noticed in the left ventricular failure, heart block
4. Bigeminal Pulse: it is accompanied by an irregular rhythm in which every other beat comes early E.g. MI
5. Weak/ thready Pulse: A small weak pulse that feels like a wire or thread on the palpation of arteries E.g. Diarrhea, Vomiting, Shock
6. Paradoxical Pulse: force or strength of the pulse wave varies feeling weaker when the patient takes in a breath.
