Collapsing The collapsing pulse of aortic regurgitation is characterised by a large upstroke followed by a rapid fall in pressure buy discount januvia 100 mg. This is best appreciated with the arm held up above the head and the pulse felt with the flat of the fingers. Alternans Pulsus alternans describes a pulse with alternating strong and weak beats. Bisferiens This is the waveform that reults from mixed aortic stenosis and regurgitation. The percussive wave P T (P) is due to ventricular systole, the tidal wave (T) is due to vascular recoil causing a palpable double pulse i. Paradoxus This is an accentuation of the normal situation with an excessive and palpable fall of the pulse Inspiration pressure during inspiration. Once the atrium is filled with blood it contracts to give the ‘a’ wave a The ‘a’ wave is lost in atrial fibrillation. The ‘a’ wave is increased in pulmonary stenosis, pulmonary hypertension and tricuspid stenosis (as a consequence of right atrial or right ventricular hypertrophy). The atrium relaxes to give the ‘x’ descent; however, the start of a ventricular contraction causes ballooning of the tricuspid valve as c it closes, resulting in the ‘c’ wave. The further ‘x’ descent is due to descent of the closed valve towards the cardiac apex. This may occur in right-sided heart Timing to systole or diastole is achieved by palpation failure, congestive cardiac failure and pulmonary em- of the carotid pulse whilst auscultating.

Investigations and procedures Heart murmurs Coronary angioplasty Heart murmurs are the result of turbulent blood flow.

Furthermore, all research activities have to be supported by adapted frameworks in Europe as well as at the national level in terms of health systems, insurers, providers, and regulatory bodies. Additionally the responsible authorities need to put in place appropriate regulatory frameworks, recognise and overcome the normative and ethical chal- lenges and, crucially, ensure that the patients’ and citizens‘ needs and interests are implemented (see also Challen- ges 1, 2, 4 and 5).
