time. Slowness of pulse, especially in the beginning of a diseased condition, is typical for a Digitalis case, and this slow pulse is often unusually hard and strong.
‘Single violent and slow beats of the heart, with sudden strong heat in the occiput and transient fainting, all of this lasting only a moment’. (The strengthening of heart contraction with decrease of pulse frequency is the desired action in allopathic use of Digitalis.) But Digitalis may also have a slow pulse that is small and even thread-like, and the remedy may also be indicated in racing, flaying, hardly perceptible pulse. In any case, there is very often some kind of arrhythmia, especially pulsus bigeminus. Absolute arrhythmia; heart beat and radial pulse may not be synchronous.
A description by Baehr: ‘Some quick beats are followed by a series of fuller and slower ones, of indefinite number. The intermissions… seldom fill a time of two pulsations; usually only one pulsation is missing after 3, 5 or 7, even 15, 16 or 18 beats – as if the heart wanted to have a break’.
A characteristic observation from a proving: ‘Pulse 60 when sitting, 72 when standing, the slightest motion made it immediately more rapid; noting the pulse while leaning backward in a reclining chair and then raising myself to slowly sitting upright, the pulse became in a moment jerky and very much smaller and weaker’. Or else: ‘The least muscular exertion renders the heart’s action laboured and intermittent’. Anxiety at heart is also an important symptom of the foxglove. ‘Pressing constrictive heartbeats, with anxiety and spasmodic pain in sternum and beneath ribs, increased on bending head and upper part of body forward’. Or else: ‘Stronger and almost audible pulsations of heart, with anxiety and constrictive pains behind the sternum’.
Sometimes there is also a feeling as if the heart were grasped by a hand which presses it slowly together (compare Cactus), especially on each intermission of the pulse.
There are also less violent manifestations of precordial anxiety, e.g. a ‘dull and disagreeable feeling’ or an ‘uneasiness’ in the region of the heart (Possart). Sudden attacks of violent and irregular palpitation, with a feeling of impending death and fearful anguish; aggravated by the slightest motion. Also: sensation of uneasiness and palpitations of the heart when climbing even a little; before the proving, these ascents had not had any action upon the organism.
