Cardiac Arrhythmia, Tachycardia

UMLS: C0039231
Basic Information
Severity Level:
Moderate
Based on 3 similar ADEs (max similarity: 0.600)
Definition:
Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.

The Introduction of Drug-AE Confidence Score Grade
Priority Level Score Range Description Evidence Characteristics
High Score ≥ 6.67
High-priority associations requiring immediate attention.
Strong evidence across multiple dimensions with high statistical significance, robust association measures, and substantial case numbers. Warrant priority pharmacovigilance action. High P-value scores (significant Adjust-P), Strong ROR/PRR values, Substantial case numbers, Complete dimensional coverage, Minimal data filtering needed.
Medium 3.33 ≤ Score < 6.67
Medium-priority associations requiring careful evaluation.
Moderate evidence quality with acceptable statistical significance and association strength. May need additional validation or monitoring before definitive action. Moderate P-value significance, Reasonable ROR/PRR measures, Adequate case numbers, Partial dimensional coverage, Some data quality considerations.
Low Score < 3.33
Low-priority associations with limited evidence strength.
May represent weak signals, insufficient data, or associations requiring extensive additional investigation before any regulatory or clinical consideration. Weak P-value significance, Low association measures, Limited case numbers, Incomplete dimensional data, Significant data filtering applied.

The Introduction of Drug-AE Severity Score Grade
Severity Level Score Range Description Typical outcomes
Minimal 0 ≤ Score ≤ 0.387
Low severity ADRs requiring minimal intervention.
Events that need medical attention to prevent permanent damage but without hospitalization or life-threatening consequences. Primarily RI (Required Intervention) outcomes, Outpatient management, Preventive measures, Early intervention prevents escalation.
Mild 0.387 < Score ≤ 0.861
Mild severity events requiring hospitalization.
Mix of intervention-required and hospitalization cases with manageable clinical outcomes and good recovery potential. Mix of RI and HO outcomes, Initial or prolonged hospitalization, Active medical management, Generally favorable prognosis.
Moderate 0.861 < Score ≤ 1.500
Moderate ADRs resulting in permanent disability.
Higher proportion of hospitalization and disability cases requiring intensive medical management and long-term care planning. Increased HO and DS outcomes, Permanent disability, Extended hospitalization, Rehabilitation required, Long-term functional impairment.
Severe 1.500 < Score ≤ 2.52
High severity life-threatening events with significant morbidity.
Notable presence of disability and life-threatening outcomes requiring emergency intervention and intensive care management. Prominent DS and LT outcomes, Life-threatening events, Emergency intervention required, ICU admission, High risk of permanent consequences.
Critical 2.524 < Score ≤ 5.000
Critical life-threatening or fatal ADRs with maximum clinical impact.
High proportion of life-threatening events and deaths with very strong drug-event associations requiring immediate regulatory action. Significant LT and DE outcomes, Fatal events, Emergency life-support measures, Immediate drug discontinuation, Regulatory safety alerts.
The Introduction of Drug-AE-Protein Confidence Score Grade
Confidence Level Relationships Description Evidence Types
Known/Valid Direct DTA relationships The drug-ADE, drug-target, and target-ADE associations are all derived from the same literature source. Experimental validation, Clinical evidence
High DT + TA + DA Two of the three associations (drug-ADE, drug-target, and target-ADE) are derived from the same literature source, while the third is validated by other literature. Multiple corroborating sources
Medium DT + TA + DA Two of the three associations (drug-ADE, drug-target, and target-ADE) are validated by separate literature sources. Partial evidence chain
Low TA + DT Only target-ADE and drug-target associations are validated by literature sources. Associative evidence only
