Disease and conditions

Sinus bradycardia & sinus arrest
This rhythm does not require treatment, unless they are causing symptoms, i.e. syncope, dizziness, tiredness and poor effort tolerance. Sinus bradycardia < 50/minute or sinus arrest with slow escape rhythm, accompanied by hypotension, strongly suggests a treatable underlying cause:

Acute Heart Failure (AHF)
Heart Failure is a clinical syndrome characterized by typical symptoms that may be accompanied by signs caused by a structural and/or functional cardiac abnormality, resulting in a reduced cardiac output and/or elevated intracardiac pressures at rest or during stress.
Acute heart failure
AHF is defined as rapid or gradual onset of signs and symptoms of heart failure that results in urgent unplanned hospitalization or Emergency Medicine Department visits. The clinical signs and symptoms are significantly life threatening if the above features occur in patients with established diagnosis with structurally heart disease categorized as Acute Decompensated Heart Failure (ADHF). The cause and immediate precipitating factor(s) of the AHF must be identified and treated to prevent further damage to the heart.
Treatment Goals
To improve clinical symptoms and outcome, management strategy should be based on clinical, laboratory and haemodynamic findings. All patient with AHF should be cared and admitted to a high care dependent unit or Intensive Care Unit.
Consider oral vasodilators in case intravenous vasodilator not available or unavailability of intensive care or high dependent unit care
• Isosorbide mononitrate 10–20mg (PO) 12 hourly
OR
• Hydralazine 25 mg (PO) 6–8 hourly. Maximum dose: 200 mg/day
Inotropes (Inotropic agents)
Indicated in patients with hypotension (SBP <90 mmHg or mean arterial BP < 60mmHg) and peripheral hypoperfusion. Dosage see in image number 2 above.
Vasopressor (norepinephrine preferably) Indicated in patients with cardiogenic shock, despite treatment with another inotrope, to increase blood pressure and vital organ perfusion

Prevention of atherosclerotic ischaemic heart disease and stroke
Cardiovascular disease (CVD) prevention is a coordinated set of actions, at the population level or targeted at an individual at risk of developing cardiovascular disease, that are aimed at eliminating or minimizing the impact of CVDs and their related disabilities.
