2. Common Causes<\/span><\/div>\n
\u2022 Lifestyle: caffeine, alcohol, stress, poor sleep.<\/span><\/div>\n
\u2022 Drugs: \u03b2-agonists (salbutamol), steroids, levothyroxine, CCBs, anticholinergics, nasal decongestants; QT-prolonging drugs (CredibleMeds.org).<\/span><\/div>\n
\u2022 Mental health: anxiety, panic, somatization.<\/span><\/div>\n
\u2022 Illicit substances: cannabis, amphetamines, cocaine.<\/span><\/div>\n
\u2022 Cardiac: ectopy, SVT, AF\/flutter, structural disease.<\/span><\/div>\n
3. History Clues<\/span><\/div>\n

\u2022 Sudden stop \u2192 paroxysmal SVT<\/span><\/div>\n
\u2022 Triggered by cold drinks \u2192 AF\/flutter<\/span><\/div>\n
\u2022 Terminated by cough\/Valsalva \u2192 AVRT<\/span><\/div>\n
\u2022 Postural triggers \u2192 AVRT (\u00b1 neck pulsations)<\/span><\/div>\n
\u2022 Exertional palpitations = red flag<\/span><\/div>\n
\u2022 Ask about impact on daily life.<\/span><\/div>\n
4. Associated Symptoms (Red Flags)<\/span><\/div>\n
\u2022 Presyncope\/syncope<\/span><\/div>\n
\u2022 Dyspnea (possible HF or fast AF)<\/span><\/div>\n
\u2022 Chest pain (CAD vs rapid HR)<\/span><\/div>\n
\u2022 Polyuria (atrial tachyarrhythmias)<\/span><\/div>\n
5. Family History Importance<\/span><\/div>\n
\u2022 Cardiomyopathies, early AF, premature CAD, ICD use.<\/span><\/div>\n
\u2022 Ask about sudden cardiac death <40 yrs (autosomal dominant risks).<\/span><\/div>\n

\u2022 12-lead ECG more useful initially than 24h Holter.<\/span><\/div>\n
\u2022 Normal ECG does not rule out arrhythmia.<\/span><\/div>\n
\u2022 Use Holter only if symptoms occur \u22653\u20134\u00d7 weekly.<\/span><\/div>\n
