Table 2 Symptoms and sign of Covid-19 infection and management in cardiomyopathies (CMP) and ion channel diseases (ICD). HFpEF: heart failure with preserved ejection fraction; HFrEF: heart failure with reduced ejection fraction

Fever

anamnesis: previous contact with Covid19+, onset, and progression, degree (>or < 37.5°), association with other symptoms

Hydratation (according to clinical status) and paracetamol

ECG monitoring in Brugada Syndrome. Consider hospitalization in high risk patients (BS type 1 with no ICD; previous syncope; persistent fever, with no response to paracetamol)

Cough

anamnesis: previous contact with Covid19+, type of cough (productive or dry), previous or recent onset, association with other symptoms

Teleconsultation

ProBNP or BNP (suspect of new onset heart failure), when possible

Consider hospitalization in high risk patients (emergency; end stage cardiomyopathies; high suspect of HFREF/HFPEF)

Dyspnoea

anamnesis: previous contact with Covid19+, type and degree, previous or recent onset, association with other symptoms

Teleconsultation

ProBNP or BNP (suspect of new onset heart failure), when possible

Consider hospitalization in high risk patients (emergency; end stage cardiomyopathies; high suspect of HFREF/HFPEF)

Fatigue

anamnesis: previous contact with Covid19+, type (i.e. myalgia, cramps, etc) and degree, previous of recent onset, association with other symptoms

Teleconsultation

When useful, suggest potassium/magnesium supplementation

ProBNP or BNP (suspect of new onset heart failure), when possible

Consider hospitalization in high risk patients (emergency; end stage cardiomyopathies; high suspect of HFREF/HFPEF)

Diarrhea

anamnesis: previous contact with Covid19+, association with other symptoms

Teleconsultation

Hydratation (according to clinical status)

Risk of hypokaliemia particularly dangerous in patients with prolonged QT (LQTs, drugs, HCM)

Potassium/magnesium supplementation
